Harry, Bobby and Curry collected stamps in the ratio of 12 : 10 : 5. After Curry gave
710 to Harry and Bobby, Curry had 600 less stamps than Harry. The number of stamps that Bobby had increased by 20%. How many stamps did Harry and Curry have in the end?
| |
Harry |
Bobby |
Curry |
| Before |
12 u |
10 u |
5 u |
| Change |
+ 1.5 u |
+ 2 u |
- 3.5 u |
| After |
13.5 u |
12 u |
1.5 u |
Number of stamps that Curry gave to Harry and Bobby
=
710 x 5 u
= 3.5 u
Number of stamps that Bobby received from Curry
=
20100 x 10 u
= 2 u
Number of stamps that Harry received from Curry
= 3.5 u - 2 u
= 1.5 u
Number of less stamps that Curry had less than Harry
= 13.5 u - 1.5 u
= 12 u
12 u = 600
1 u = 600 ÷ 12 = 50
Number of stamps that Harry and Curry had
= 13.5 u + 1.5 u
= 15 u
= 15 x 50
= 750
Answer(s): 750
