Luke had
38 as many coins as Usha. After Luke bought another 34 coins, he had 16 less coins than Usha. How many coins did Luke have at first?

| Before |
3 u |
8 u |

+ 34 |

| After |
3 u + 34 |
8 u |
Usha had 16 more coins than Luke in the end. So, if Luke had another 16 coins, he would have the same number of coins as Usha.
8 u = 3 u + 34 + 16
8 u - 3 u = 34 + 16
5 u = 50
1 u = 50 ÷ 5 = 10
Number of coins that Luke had at first
= 3 u
= 3 x 10
= 30
Answer: 30
