Question

Find a number whose fifth part increased by30 is equal to its fourth part increased by 23?????

Answer 1

Let the number be a

According to question

a/5 + 30 = a/4 + 23

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

=> 7 = (5a - 4a) / 20

=> 140 = a

=> a = 140

Required number = 140

Answer 2

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.
