Question

Q. Ravi has ₹68 in the form of fifty Paise coins and twenty five paise coins. If the number of 25 paise coins are twice the number of 50 paise coins, how many coins of each kind does he have?​

Answer 1

Step-by-step explanation:

Let ravi has 'x' 50-paise coins & 'y' 25-paise coins.

he has rs 34

So rs 1 = 100 paise

rs 34 = 34*100 = 3400 paise

50x + 25y = 3400 ----------- (1)

Given that , y = 2x ------------(2)

from equation (1) & (2) we get

50x + 25*(2x) = 3400

50x + 50x = 3400

100x = 3400

x = 34

From (2) we get

y = 2x = 2*34 = 68

So,

Number of 50-paise coins = 34

Number of 25-paise coins = 68

Answer 2

Answer:

Numner of 50 paise coins are 68 and number of 25 paise coins are 136.

Step-by-step explanation:

Let,

Number of 50 paise coin be=x

Number of 25 paise coin be=2x

Converting 50 paise to 1 rupee we get=x/2

Converting 25 paise to 1 rupee we get=2x/4

Conditionally,

X/2+2x/4=68

Or, x/2+x/2=68

Or, 2x/2=68

Therefore, x=68

Hence, 50 paise coins=68 coins

Hence, 25 paise coins=68*2 coins

=136 coins

Ans: The number of 50 paise coins are 68 and there are 136 25 paise coins.
