Question

the weight two bags are in ratio 7:6 the total weight of both bags are 91 kg find the weight of each bag

Answer 1

let the weight of the bags be 7x and 6x
so
7x+6x=91
13x=91
x=91÷13
x=7 kg
so weight of first bag is 7x=7(7)=49 kg
weight of second bag is 6x=6(7)=42 kg

Answer 2

let the ratio be 7x and 6x

therefore,
7x + 6x = 91
13x = 91
x = 91/13
x = 7

weight of first bag = 7x = 7x7= 49kg(ans)
weight of second bag = 6x = 6x7 = 42kg(ans)

total weight = 49+42 = 91kg(proved)
