Answer 2

Step-by-step explanation:

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

Solution:

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
