Answer 1

Answer:

Step-by-step explanation:

(H + A) 1 day work = 1/10

(A + R) 1 day work = 1/15

(R + H) 1 day work = 1/20

2(H + A + R) 1 day work = 1/10 + 1/15 + 1/20

=6+4+3/60 = 13/60

(H + A + R) 1 day work = 13/2 x 60 = 13/120

Himanshu 1 day work = 13/120 - 1/5

= 13 - 8/120 = 1/24

Himanshu will complete work in 24 days
