#Q-274. While walking with 13/11th of the speed a man reaches 3 min. early to his office. Find the original time taken by him to reach office.
Solution-: Ritika ji, aapne question English me send kiya hai lekin hum issko hindi me solve karenge.
Question me diya hai "Ek aadmi jab apni original speed ke 13/11th speed se chalta hai to wo 3 minutes jaldi office pahuch jaata hai. Uski original speed bataye"
Suppose karte hai, man ki original speed = s aur original time = t, then d = s×t .............(i)
Ab according to the question, new speed (s') = 13s/11 aur new time (t') = t-3, then d = s'×t'
⇒ d = (13s/11)×(t-3) ....(ii)
Eq(i) aur (ii) ko equal karne par:
⇒ s×t = (13s/11)×(t-3)
⇒ 11st = 13s(t-3)
⇒ 11st = 13st-39s
⇒ 39s = 13st-11st
⇒ 39s = 2st
⇒ 39 = 2t
⇒ t = 39/2
⇒ t = 19.5 minutes Ans.

#Q-293. 395 rupya ko a, b, c me is prakaar bata gya ki b ko a se 25% adhi ttha c se 20% adhik to a ka bhaag kya huaa
Solution-: Suppose karte hai ki, a ko X rupya aur c ko Y rupya mila.
Tab question ke anusaar-:
• Jab a ko X rupya mila tab,
b = X+25%X
= X+X/4
= 5X/4
• Jab c ko Y rupya mila tab,
b = Y+20%Y
= Y+Y/5
= 6Y/5
toh iss prakar se-:
⇒ 5X/4 = 6Y/5
⇒ Y = 25X/24
Hum jaante hai ki, a+b+c = 395
∴ X+5X/4+Y = 395
⇒ X+5X/4+25X/24 = 395
⇒ 79X/24 = 395
⇒ X = 395×24/79
= 9480/79
= 120
Isliye a ka bhaag 120 rupya huaa. Answer
Tab question ke anusaar-:
• Jab a ko X rupya mila tab,
b = X+25%X
= X+X/4
= 5X/4
• Jab c ko Y rupya mila tab,
b = Y+20%Y
= Y+Y/5
= 6Y/5
toh iss prakar se-:
⇒ 5X/4 = 6Y/5
⇒ Y = 25X/24
Hum jaante hai ki, a+b+c = 395
∴ X+5X/4+Y = 395
⇒ X+5X/4+25X/24 = 395
⇒ 79X/24 = 395
⇒ X = 395×24/79
= 9480/79
= 120

#Q-304. दो अंको की किसी संख्या का 7/9 भाग उस संख्या के 9/11 भाग से 4 कम है तो उस संख्या के अंको के योग क्या है ?
Solution-: Maana 2 anko ki sankhya = 10a+b
Ab (10a+b) ka 7/9 bhaag
= 7 (10a+b)
9
aur (10a+b) ka 9/11 bhaag
= 9 (10a+b)
11
Ab question ke according ,
⇒ 7 (10a+b)+4 = 9 (10a+b)
9 11
⇒ 70a + 7b +4 = 90a + 9b
9 9 11 11
⇒ 90a - 70a + 9b - 7b = 4
11 9 11 9
⇒ (810 - 770)a + (81 - 77)b = 4
99 99
⇒ 40a + 4b = 4
99 99
⇒ 40a+4b = 4×99
⇒ 10a+b = 99
Matlab 2 anko ki sankhya = 10a+b = 99
Isliye anko ka yog = 9+9 = 18 Ans.
Ab (10a+b) ka 7/9 bhaag
= 7 (10a+b)
9
aur (10a+b) ka 9/11 bhaag
= 9 (10a+b)
11
Ab question ke according ,
⇒ 7 (10a+b)+4 = 9 (10a+b)
9 11
⇒ 70a + 7b +4 = 90a + 9b
9 9 11 11
⇒ 90a - 70a + 9b - 7b = 4
11 9 11 9
⇒ (810 - 770)a + (81 - 77)b = 4
99 99
⇒ 40a + 4b = 4
99 99
⇒ 40a+4b = 4×99
⇒ 10a+b = 99
Matlab 2 anko ki sankhya = 10a+b = 99
Isliye anko ka yog = 9+9 = 18 Ans.

#Q-319. 1 ,2^1/2 ,3^1/3 ,6^1/6 to inmese badi sankhya kya hogi (please solution with explannation)
Solution-: Mahadev ji, iss question ko hum ek shortcut tricks se solve karte hai.
Tricks-: Step-1. Sabse pahle sabhi number ke power 1/2, 1/3, 1/6 ke denominator 2, 3 aur 6 ka L.C.M nikalenge.
2 | 2, 3, 6
3 | 1, 3, 3
| 1, 1, 1
2, 3 aur 6 ka L.C.M. = 2×3 = 6
Step-2. Sabhi power 1/2, 1/3 aur 1/6 me L.C.M. = 6 se multiply karenge.
• 1/2 × 6 = 3
• 1/3 × 6 = 2
• 1/6 × 6 = 1
Step-3. Ab sabhi number 1, 2, 3, 6 par new power lagakar solve karenge.

#Q-319. 1 ,2^1/2 ,3^1/3 ,6^1/6 to inmese badi sankhya kya hogi (please solution with explannation)
Solution-: Mahadev ji, iss question ko hum ek shortcut tricks se solve karte hai.
Tricks-: Step-1. Sabse pahle sabhi number ke power 1/2, 1/3, 1/6 ke denominator 2, 3 aur 6 ka L.C.M nikalenge.
2 | 2, 3, 6
3 | 1, 3, 3
| 1, 1, 1
2, 3 aur 6 ka L.C.M. = 2×3 = 6
Step-2. Sabhi power 1/2, 1/3 aur 1/6 me L.C.M. = 6 se multiply karenge.
• 1/2 × 6 = 3
• 1/3 × 6 = 2
• 1/6 × 6 = 1
Step-3. Ab sabhi number 1, 2, 3, 6 par new power lagakar solve karenge.
1, 2³, 3², 6¹
= 1, 8, 9, 6
Inmese badi sankhya = 9

#Q-320. X4 - 40X2 = -39 solve please
Solution-: हैैलो , hume lagta hai ki, aapka question kuch iss prakar se hai:
x⁴- 40x² = -39
x⁴- 40x²+39 = 0 ........(i)
Maana x⁴ = z² and x² = z
Toh equation (i) me x⁴ aur x² ki value rakh kar solve karne par,
⇒z²-40z+39 = 0
⇒z²-(39+1)z+39 = 0
⇒z²-39z-z+39 = 0
⇒z(z-39)-1(z-39) = 0
⇒(z-39)(z-1) = 0
Jab (z-39) = 0 toh z = 39
∴ x² = 39
x = √39
Jab (z-1) = 0 toh z = 1
∴ x² = 1
x = √1 = 1
Toh x = √39 aur 1 Answer.

Solution-: Suppose karte hai ki, 25 ko do bhaag "x" aur "y" me thoda gaya.
Tab, x+y = 25 ....(i)
aur 9x+5y = 139 ......(ii)
Ab eq(i) me 9 se multiply karne par,
⇒ 9x+9y = 225 .....(iii)
Ab eq(iii) me se eq(ii) ko subtract karne par,
⇒ 4y = 86
⇒ y = 21.5
Ab "y" ki value eq(i) me rakh kar solve karne par,
⇒ x+21.5 = 25
⇒ x = 25-21.5
= 3.5

#Q-361. 25 को दो भागो में इस प्रकार तोड़े की पहले भाग के 9गुने में दुसरे भाग का 5 गुने जो जोड़कर 139 बनता है
Solution-: Suppose karte hai ki, 25 ko do bhaag "x" aur "y" me thoda gaya.
Tab, x+y = 25 ....(i)
aur 9x+5y = 139 ......(ii)
Ab eq(i) me 9 se multiply karne par,
⇒ 9x+9y = 225 .....(iii)
Ab eq(iii) me se eq(ii) ko subtract karne par,
⇒ 4y = 86
⇒ y = 21.5
Ab "y" ki value eq(i) me rakh kar solve karne par,
⇒ x+21.5 = 25
⇒ x = 25-21.5
= 3.5
Toh 25 ko 21.5 aur 3.5 me todenge. Answer.

#Q-389. 50 को दो भागों में विभाजित करें जिससे उनके व्युत्क्रमों का योगफल 1/12 हो ।
Solution-: Santosh ji, इस question को हम इस प्रकार से Solve कर सकते है -
माना 50 को दो भागों a और b में विभाजित किया जाता है, तब a+b = 50 ............(i)
और फिर Question के अनुसार ,
1 + 1 = 1
a b 12
a + b = 1
ab 12
50 = 1
ab 12
ab = 600
अब (a - b)² = (a + b)² - 4ab का use करने पर -
(a - b)² = (a + b)² - 4ab
= (50)² - 4×600
= 2500 - 2400
= 100
(a - b)² = 100
⇒ a - b = √100 = 10 .......... (ii)
समीकरण (i) और (ii) को जोड़ने पर -
⇒ (a + b) + (a - b) = 50 + 10
⇒ 2a = 60
⇒ a = 60/2
⇒ a = 30
अब समीकरण (i) में a = 30 रखने पर -
⇒ 30 + b = 50
⇒ b = 50 - 30
⇒ b = 20
अतः 50 को 30 और 20 में विभाजित करेंगे । Ans.

#Q-392. 1/sin/cos ko kaise solve kare Bahut log cos ko 1se devide karke cos ka sin me multiply karte hai to kai log direct cos ka 1 multiply karte hai
Solution-: Shivkaran ji, 1/sin/cos question me 2 conditions ho sakta hai.
(1). ho sakta hai ki ye question kuch iss prakar se ho
1/(sin/cos) = ??
(2). Ya phir ho sakta hai ye question kuch iss prakar se ho
(1/sin)/cos = ??
Hum dono conditions ko solve karna aapko sikha de rahe hai.
Condition-1 . 1/(sin/cos) = ?? ko iss prakar se solve kar sakte hai -
(1). Sabse pahle 1 ko same to same likhkar sin/cos ko ulta cos/sin likhkar multiply karenge.
1 = 1 × cos
sin sin
cos
= 1 × cos
sin
= cos Ans.
sin
Condition-2 . (1/sin)/cos = ?? ko iss prakar se solve kar sakte hai -
(1). Sabse pahle cos ke niche bate ("/") ki line khichkar 1 likhe.
1 1
sin = sin
cos cos
1
(2). Ab 1/sin ko same to same likhkar cos/1 ko ulta 1/cos likhkar multiply kar dena.
1 1
sin = sin
cos cos

#Q-397. 5√3+7√2-√6-23÷√2+√3+√6
Solution-: 5√3+7√2-√6-23÷√2+√3+√6
= (5√3+√3)+(√6-√6)+(7√2-23÷√2)
= (6√3)+(0)+(7√2-23÷√2)
= 6√3+(7√2-23÷√2)
= 6√3×√2+7√2×√2-23
√2
= 6√6+14-23
√2
= 6√6-9
√2
Numerator aur denominator me √2 se multiply karne par-:
= (6√6-9)×√2
√2×√2
= 6√12-9√2 Ans.
