Question

Answer

At first —
Allan : 3u
Bala : 5u
Chee Wee : 2p

After —
Allan : 3u
Bala : 5u/2 = 2.5u
Chee Wee : 2p/2 = 1p

2.5u ——- 1p + 75
1p ——- 2.5u – 75
3u + 2.5u + 1p = 5.5u + 2.5u – 75 = 8u – 75 ——- 341
1u ——-(341 + 75)/8 = 52
2p ——– (2.5 x 52 – 75) x 2 = 110

Ans : 110 cards.

  Allan Bala Chee Wee
At first 6u 10u 2p
B & C lost 1/2   -5u -1p
In the end 6u 5u 1p
       

Given: B had 75 more than C -> 1p = 5u – 75

Total -> 341

6u + 5u + (5u – 75) = 341

16u = 416

u = 26

1p = 5u – 75 = 55

Chee Wee had 2p = 110 cards at first
