Linda has 2 times as many cards as Usha. Usha has
57 as many cards as Lucy. If the three of them have a total of 154 cards, how many cards does Linda have?
| Linda |
Usha |
Lucy |
| 2x5 |
1x5 |
|
| |
5x1 |
7x1 |
| 10 u |
5 u |
7 u |
The number of cards that Usha has is repeated. Make the number of cards that Usha has the same. LCM of 1 and 5 is 5.
Total number of cards that the three of them have
= 10 u + 5 u + 7 u
= 22 u
22 u = 154
1 u = 154 ÷ 22 = 7
Number of cards that Linda has
= 10 u
= 10 x 7
= 70
Answer(s): 70
