Question

Divide rupees 2400 among a b and c in the ratio 2:3:5 if b gives rupees 20 to a from his share find the ratio of the new shate

Answer 1

Step by step explanation

a:b:c = 2:3:5
total ratio = 2+3+5=8
Now,
Share of a = 2/8 x 2400 = 480 rs
Share of b = 3/8 x 2400 = 720 rs
Share of c = 5/8 x 2400 = 1200 rs

Now if b gives 20 rs to a, then their new share would be
a = 480 + 20 = 500 rs
b = 720 - 20 = 700 rs
c = 1200 rs

Now
ratio a:b = 500 / 700
= 5:7
ratio b:c = 700/ 1200
= 7:12
Ratio a:b:c = 5x7 : 7x7 : 7x17
= 35 : 49 : 119
= 5 : 7 : 17 ans
