Question

Find a number whose fifth part increased by 30 is equal to its fourth part decreased by 30.
​

Answer 1

Answer:

Let the number be x

Its fifth part is =5x

Its fourth part is =4x

According to the given condition,

(5X)+30=(4X)−30

(5X)−(4X)=−30−30

204X−5X=−60

−X=−60×20

−X=−1200

X=1200.

Hence, the number is 1200.
