Question

Chandani purchased some parrots. 20% flew away and 5% died.of he remaining,45%were sold now33 parrots remain how many parrots were purchased

Answer 1

Total number of Parrot = x

now we will setup a equation

x 20/100 + x 5/100 + x 45/100 + 33 = x

( it means 20% of x + 5% of x + 45% of x + 33 is equal to the total number of parrots that is x)

70x/100 + 33 = x

70x + 3300 = 100x

3300 = 100x - 70x

3300/30 = x

x = 110

Total number of parrot purchased = 110 unit
