Question

6. Find a number whose one-third part exceeds its one-fifth part by 20 ​

Answer 1

Answer:

150

Step-by-step explanation:

Let the number be 'y'

1/3 of y = y/3

1/5 of y = y/5

=> (equation)   y/3 - y/5 = 20

=>(By LCM)  (5y - 3y)/15 = 20

=> 2y/15 = 20

=> y = 20 x 15 / 2

=> y = 10 x 15

=> y = 150
