Question

Ram has 3 times as many Rs2 coins as he has Rs5 coins. If he has in all a sum of Rs77, how many coins of Rs2 does he have?

Answer 1

Let us take number of 5 rupees coins as X and number of 2 rupees coins as Y

Amount of 5 rupees coin will make = 5X

Amount of 2 rupees coin will make = 3Y

Number of 2 rupees coin = 3 \times 5\ rupees.3×5 rupees.

Number of 2 rupees coins are equal to 3X and number of 5 rupees is X

Total amount = 2( 3X ) + 5X = 11X

Now we can equate the amount which 11X = 77

X = 7

Now as we know the number of 2 rupees coin is 3X and number of 5 rupees coin is X, that means

Number of 2 rupees coins = 21 and number of 5 rupees coins = 7

Answer 2

Answer:

no. 5 rupee coins = x

no. 2 rupee coins =3x

value of 5 rupee coins = 5 times x

value of 2 rupee coins = 2 times 3x

now according to question

5x + 6x = ₹77

11x = ₹77

x = ₹7

now you can solve the rest
