X = 30
Boys(avg) = 44
No of boys = 25
25*44 == 1100

Pls explain in detail

x- y = 6*60/18 = 20
x+y = 12*60/12 = 60

x = 40
y = 20

Y ko double kr rha = 40
Time bhi double bol rha

x-y = 6*60/36 = 10

x = 50

10/40 = 25% increase

21a = 15b , a : b = 5 : 7

Tym = 48×5)/12= 20 days

35%= 126
100%= 360

360 : 540 = 2 : 3 , q = 50%

360 × 1.3= 468₹

Explain

d1 = 432/18+ 4 = 28
d2 = 80/4 × 80%= 16

Area = 1/2 × 28 × 16 = 224 cm²

220 × (√3-1) ≈ 161.05 meters

5×12 : 10 ×10 : 6×20 = 3 : 5 : 6

14 = 350000
5 = 125,000₹

1/4 = 5/12(1- 240/x)

X = 50 24x = 1200

Kerosene = 1 = 200 liters

C=100%+300)90%=90%+270
T=100*115%=>115%

205%=1845
100%=900. 100%+300=>1200

a - b = 3)*115
115b + 90a = 2115

205a == 2460
100a ==> 1200
