Answer 2

Answer:

Given : Inspired by the “Swachh Bharat mission”, Priya and her friends Sunita, Kavya and Hema decided to clean their society park. Her friends clean 2/5, 1/3 and 1/4 part of the park respectively

To Find :  How much part of the park will be left for Priya to clean? *

( a ) 1/60

( b ) 29/60

( c ) 10/20

( d ) none of these

Solution:

Sunita = 2/5

Kavya = 1/3

 Hema = 1/4

Rest  = Priya

Let say total work  = 60x

Sunita = (2/5)60x  = 24x

Kavya = (1/3) 60x  = 20x

 Hema = (1/4)60x  = 15x

 Priya = 60x - (24x + 20x + 15x)  =  x

part of the park will be left for Priya  = x/60x  = 1/60
