Question

If 3/5 of a number exceed it's 2/7 by 44 find the number

Answer 1

let the no. be x
3x/5=2x/7+44
3x/5=2x/7+308/7
3x/5=(2x+308)/7
(3x×7)=(2x+308)×5
21x=10x+1540
21x-10x=1540
11x=1540
x=1540 /11
x=140

Answer 2

Let x be the no.
ATQ
3/5 x - 2/7 x =44
21x - 10x / 35 = 44
11x/ 35 =44
11x = 44 × 35
x = 44 × 35/ 11
x = 4 × 35 = 140
