Question

Divide 3450 among a,b and c in the ratio 3:5:7.

Answer 1

Hi,

a:b:c = 3 : 5 : 7

Let the shares of a, b and c be 3x, 5x and 7x respectively.
Given,
Sum = 3450
3x + 5x + 7x = 3450
15x = 3450
x = 3450/15 = 230

So,
a's share = 3x = 3*230 = 690
b's share = 5x = 5*230 = 1150
c's share = 7x = 7*230 = 1610

Hope it helps!

Answer 2

Given ratio=3:5:7
Total ratio=15
Amount of A=3/15*3450=690
Among of B=5/15*3450=1150
Amount of C=7/15*3450=1610
