| Before |
7 u |
4 u |
4 u |
| Change |
+ 1.6 u |
+ 1.6 u |
- 3.2 u |
| After |
8.6 u |
5.6 u |
0.8 u |
Number of stamps that Clint gave to Ahmad and Asher
=
45 x 4 u
= 3.2 u
Number of stamps that Asher received from Clint
=
40100 x 4 u
= 1.6 u
Number of stamps that Ahmad received from Clint
= 3.2 u - 1.6 u
= 1.6 u
Number of less stamps that Clint had less than Ahmad
= 8.6 u - 0.8 u
= 7.8 u
7.8 u = 156
1 u = 156 ÷ 7.8 = 20
Number of stamps that Ahmad and Clint had
= 8.6 u + 0.8 u
= 9.4 u
= 9.4 x 20
= 188
Answer(s): 188
