Question

Divide 4970 among a, b and c such that a gats 1/5 of what b gets and the ratio of b and c is 6:7

Answer 1

here,a=1/5b=1/5.6x=6/5x
       a=6/5x
        b=6x
        c=7x
a+b+c=4970
6x/5+6x+7x=7970
after taking L.C.M.
71x/5=4970
71x=4970*5=24850
x=24870/71=350
x=350
by substituting x value,
a=420
b=2100
c=2450

Answer 2

Take b as 6x and c as 7x. A=1/5 of b (6x)
