Question

John, Kevin, and Andrew are counting their pennies. John has three times as many pennies as Kevin. If John and Andrew put their pennies in the same container, they'll have 266 pennies. However, if Kevin and Andrew put their pennies together, they will have 198 pennies. How many pennies does John have?

Answer 1

102 pennies

Explanation:

Let the number of pennies owned by John, Kevin, and Andrew be J , K and A respectively

Given that John has three times as many pennies as Kevin then

J = 3K

If John and Andrew put their pennies in the same container, they'll have 266 pennies then

J + A = 266 Since J = 3K

3K + A = 266

However, if Kevin and Andrew put their pennies together, they will have 198 pennies

K + A = 198

Subtract K + A = 198 from 3K + A = 266

2K = 68

K =68/2 = 34 pennis

J = 3K J = 3 * 34

= 102 pennies

John has 102 pennies
