Answers
Given : D, C, B and A have a certain sum of money each in the ratio of 3:3:5:7 respectively.
D gives 10% of what he has to C
B give 10% of what he was to A.
To Find : the new ratio of DCBA
Solution:
D, C, B and A have a certain sum of money each in the ratio of 3:3:5:7
Let say their sums are
D = 300k
C = 300 k
B = 500k
A = 700k
D gives 10% of what he has to C
=> D new share = 300k - (10/100)300k = 270k
C new share = 300K + 30k = 330k
B give 10% of what he has to A.
=> B new share = 500k - (10/100)500k = 450k
A new share = 700K + 50k =750k
270k : 330k : 450k : 750k
27 : 33 : 45 : 75
9 : 11 : 15 : 25
the new ratio of DCBA is 9 : 11 : 15 : 25
