Three bags, R, S and T contained a certain number of postcards. Bag T contained
27 as many postcards as R and S combined. There were 96 more postcards in Bag R than in Bag T. Bag S contained 162 more postcards than Bag T. How many postcards were in Bag S?
| Bag R |
Bag S |
Bag T |
Total |
| 7 u |
2 u |
9 u |
| 2 u + 96 |
2 u + 162 |
|
|
The total number of postcards in Bag R and Bag S is repeated.
2 u + 96 + 2 u + 162 = 7 u
4 u + 258 = 7 u
7 u - 4 u = 258
3 u = 258
1 u = 258 ÷ 3 = 86
Number of postcards in Bag S
= 2 u + 162
= 2 x 86 + 162
= 334
Answer(s): 334
