1 u + 26
|
Change |

+ 51 |
After |
1 u |
1 u + 26 + 51 = 1 u + 77 |
At first, Vaidev had $25 more than Irene. After giving to Irene, he had $77 less than Irene. This means he gave Irene more than $25.
Additional amount that Vaidev gave to Irene
= (77 - 25) ÷ 2
= 52 ÷ 2
= $26
Total amount that Vaidev gave to Irene
= 26 + 25
= $51
Answer(s): $51
