Three bags, J, K and L contained a certain number of marbles. Bag L contained
115 as many marbles as J and K combined. There were 52 more marbles in Bag J than in Bag L. Bag K contained 143 more marbles than Bag L. How many marbles were in Bag K?
Bag J |
Bag K |
Bag L |
Total |
15 u |
1 u |
16 u |
1 u + 52 |
1 u + 143 |
|
|
The total number of marbles in Bag J and Bag K is repeated.
1 u + 52 + 1 u + 143 = 15 u
2 u + 195 = 15 u
15 u - 2 u = 195
13 u = 195
1 u = 195 ÷ 13 = 15
Number of marbles in Bag K
= 1 u + 143
= 1 x 15 + 143
= 158
Answer(s): 158
