Question

If two no.s are in the ratio 3:5.And 25% of the first number is 30,then what is the 35%of the second number?

Answer 1

ans : 70
x/y=3/5
25x=3000
x=120
y=5x/3 therefore y=70

Answer 2

two numbers are in ratio = 3:5
let they are 3x and 5x

25% of 3x = 30
⇒ 3x * (25/100) = 30
⇒ 3x = 30*100/25
⇒ 3x = 120
⇒ x = 120/3 = 40

other number = 40*5 = 200
35% of 200 = 35/100 * 200 = 70
