The total number of marbles in Basket H, Basket J and Basket K was 136. ³₇ of the marbles from Basket H and 16 marbles from Basket J were removed. More marbles were then added into Basket K until the number of marbles in it was tripled. The ratio of the number of marbles in Basket H to Basket J to Basket K became 4 : 2 : 3.

1. How many less marbles were there in Basket J than Basket H at first?
2. Find the total number of marbles in Basket J and Basket K in the end.

	Basket H	Basket J	Basket K	Total
Before	7 u	2 u + 16	1 u	136
Change	- 3 u	- 16	+ 2 u
After	4 u		3 u
Comparing the marbles  in the end	4 u	2 u	3 u

(a)
Total number of marbles at first
= 7 u + 2 u + 16 + 1 u
= 10 u + 16

10 u + 16 = 136
10 u = 136 - 16
10 u = 120

1 u = 120 ÷ 10 = 12

Number of less marbles in Basket J than Basket H at first 
= 7 u - (2 u + 16)
= 7 u - 2 u - 16
= 5 u - 16
= 5 x 12 - 16
= 60 - 16
= 44

(b)
Total number of marbles in Basket J and Basket K in the end
= 2 u + 3 u
= 5 u
= 5 x 12
= 60 

Answer(s): (a) 44; (b) 60
