Question

Lakhan's kiddy bank has only 2-rupees and 5-rupees coins. The total value of the coins is 165. If the number of 5- rupee coins is five more than the number of 2- rupee coins,find the number of each type of coins in his kiddy bank​

Answer 1

Answer:

20 and 25

Step-by-step explanation:

Let the number of 2 rupee coins be x

Therefore, number of 5 rupee coins is (x+5)

Therefore, value of 2 rupee coins is 2x   and,

                  Value of 5 rupee coins is 5(x+5) = 5x + 25

Total value of 5 rupee and 2 rupee coins = 2x + (5x + 25)

According to the Question,

2x+5x+25 = 165

or, 7x = 165 - 25

or, x = 140/7 = 20

therefore,

the number of 2 rupee coins = x = 20

the number of 5 rupee coins = (x+5)= 20+5 = 25
