Solution-: According to BODMAS Rule -:

58÷9[{49+94(81÷6 of 63)}]-68+2

= 58÷9[{49+94(81÷6×63)}]-68+2

= 58÷9[{49+94(27/2 × 63)}]-68+2

= 58÷9[{49+94(27×63)/2}]-68+2

= 58÷9[{49+94(1701)/2}]-68+2

= 58÷9[{49+47×1701}]-68+2

= 58÷9[{49+79947}]-68+2

= 58÷9[79996]-68+2

= 58÷9×79996-68+2

= 6.44×79996-68+2

#Q-418. 1000 ke andhar me 4 se kitne no. Divide honge kese nikale

Solution-: Suman ji, hum jaante 1 se 1000 ke andhar 4 divide hone waale number iss prakar se hai-:

4, 8, 12, . . . 988, 992, 996

【Note-: 4, 8, 12, . . . 988, 992, 996 ek samantar shreni (arithmetic progression) hai. Issliye hum iss question me issi concept ka use karenge.】

Ye padhiye-: Arithmetic progression | Samantar shreni Basic concept | 10 Question with Solution Hindi

Maana 4, 8, 12, . . . 988, 992, 996 ke beech total "n" numbers jo 4 se divide honge. Tab nth number = 996, a = 4 aur d = 8-4 = 4

Ab A.P. nth number ke formula a_n = a+(n-1)×d

⇒ 996 = 4+(n-1)×4

⇒ 996 = 4+4n-4

⇒ 996 = 4n

⇒ n = 996/4

⇒ n = 249

Isliye 1000 ke andhar me 249 number 4 divide honge. Ans.

#Q-419. 13 saal pahle a , b se 6 guna bada tha , 2 saal bad a,b se 3 guna bada ho jayega . a and b ki age pata kariye

Solution-: Maana "a" ki present age = x saal aur "b" ki present age = y saal

Toh, 13 saal pahle, "a" ki age = x-13 saal aur "b" ki age = y-13 saal

Ab question ke anusaar-:

x-13 = 6(y-13)

x-13 = 6y-78

x-6y = 13-78

x-6y = -65 .................(i)

Phir, 2 saal baad, "a" ki age = x+2 saal aur "b" ki age = y+2 saal

Ab question ke anusaar-:

x+2 = 3(y+2)

x+2 = 3y+6

x-3y = 6-2

x-3y = 4 ........................(ii)

Equation (i) me se equation (ii) ko subtract karne par:

x-6y = -65

x-3y = 4

- + -

-3y = -69

y = 69/3

y = 23

Ab Equation (i) me y = 23 rakhne par:

x-6y = -65

x-6×23 = -65

x-138 = -65

x = 138-65

x = 73

Isliye, "a" ki age 73 years aur "b" ki age 23 years hai. Ans.

#Q-423. Ek number or uus number ka 2/5 ka 3/7 ydi 108 ho to number kya hoga

Solution-: Priya ji, iss question ko hum iss prakar se solve kar sakte hai :

Maana wo number = x

Ab x ka 2/5 = x × 2/5

= 2x/5

phir 2x/5 ka 3/7 = 2x/5 × 3/7

= 6x/35

Aur diya hai ki, 6x/35 = 108

⇒ x = (108×35)/6

⇒ x = 630

Isliye, wo number 630 hoga. Ans.

#Q-431. ek vrat ki trijya me 25% ki kami karne per eski paridhi me kitni kami hogi

Solution-: Mansi ji, iss question ko hum iss prakar se solve kar sakte hai:

Maana ek vrit (circle) jiski trijya (radius) = r

Tab, iss vrit (circle) ki paridhi (circumference) = 2π×trijya

= 2πr

Ab, trijya me 25% ki kami karne par-:

r × 25/100 = r × 1/4

= r/4

Toh, Naye (new) vrit ki trijya

= r - r/4

= (4r-r)/4

= 3r/4

Ab, Naye vrit ki paridhi

= 2π×trijya

= 2π×3r/4

= 3πr/4

∴Iski paridhi me kami

= 2πr - 3πr/4

= (8πr - 3πr)/4
