Question

Find a number whose fifth part incresaed by 30 is equal to its fourth part increase dy 23???

Answer 1

Let see your answer !!!!!

Let the required number be x. Then,

according to question ,

x/5 + 30 = x/4 + 23

=> x/5 - x/4 = 23 - 30

=> 4x - 5x/20 = - 7

=> - x/20 = - 7

=> - x = - 7 × 20

=> - x = - 140

=> x = 140

Hence , the required number is 140.
