Betty has 5 times as many puffs as Yoko. The total number of Betty's and Yoko's puffs is 8 times of Pamela's. Betty and Yoko have 210 puffs more than Pamela's. How many more puffs does Betty have than Yoko?
| Betty |
Yoko |
Pamela |
| 5x4 |
1x4 |
|
| 8x3 |
1x3 |
| 20 u |
4 u |
3 u |
The total number of puffs that Betty and Yoko have is repeated. Make the total number of puffs that Betty and Yoko have the same. LCM of 6 and 8 is 24.
Total number of puffs that Betty and Yoko have
= 20 u + 4 u
= 24 u
Number of more puffs that Betty and Yoko have than Pamela
= 24 u - 3 u
= 21 u
21 u = 210
1 u = 210 ÷ 21 = 10
Number of more puffs that Betty has than Yoko
= 20 u - 4 u
= 16 u
= 16 x 10
= 160
Answer(s): 160
