Comparing the television

124 more |
|
|
After |
3 u |
+ 186 |
5x2 =
10 u |
|
124 ÷ 2 = 62
3 x 62 = 186
5 x 62 = 310
Total amount that Vaidev and Ahmad had at first
= 5 u + 310 + 12 u
= 17 u + 310
17 u + 310 = 888
17 u = 888 - 310
17 u = 578
1 u = 578 ÷ 17 = 34
Amount that Vaidev had at first
= 5 u + 310
= 5 x 34 + 310
= 170 + 310
= $480
Answer(s): $480
