Bhairav collected Rs.600 in his piggy bank by putting in Rs.2 and Rs.5 coins. The number of Rs.5 coins are twice as many as Rs.2
Anna [14]

Answer:

100 Rs 5 coins and 50 Rs 2 coins

Step-by-step explanation:

Bhairav collected Rs.600 in his piggy bank by putting in Rs.2 and Rs.5 coins. The number of Rs.5 coins are twice as many as Rs.2 coins

Let x be the number of 5 coins

and y be the number of 2 coins

The number of Rs.5 coins are twice as many as Rs.2 coins

x=2y

5x+2y=600

Replace x with 2y

5x+2y=600\\5(2y)+2y=600\\10y+2y=600\\12y=600\\y=50

x=2y\\x=2(50)\\x=100

So 100 Rs 5 coins and 50 Rs 2 coins
