Question Example with Solution 2

Heres another similar question which requires similar concept to the previous post.

A had 60 more stamps than B. they each gave some of their stamps to their friends.the number of stamps B gave away was 2/5 of the number of stamps A had at first. The number of stamps A gave away was 2/3 of the number of stamps B had at first. both had an equal number of stamps left. How many stamps did A had at first?

Since A has 60 more than B at first,

A has to give away 60 more stamps compared what B gave away in order for them to be left with equal amount in the end.

Since A gave away 2/3 of B and B gave away 2/5 of A,

2/3 of B is 60 more than 2/5 of A.

With the aid of a model,

2 units = 150

1 unit = 75

5 units = 75 x 5 = 375

Ans: 375 stamps
