Ira can do a piece of work in 10 days, Nisha can do it in 15 days and Isha can do it 20 days. All three of them started the work together. However, Ira left after 2 days and Nisha left after 4 days. How long will Isha have to work for to complete the task?

work…………….60

Ira………………6

Nisha…………4

Isha…………..3

2(13) + 2( 7) + x(3) = 60

26+14+3x = 60 >> x = 20/3

can you explain in detail please i mean step by step bcz i did not understand above procedure

ira worked for 2 days so 1/10 * 2 = 1/5

nisha – 1/15* 4

so 1/5 + 4/15 + 1/20 * x = 1

x = 32/3

so more days nisha work = 32/3 – 4 = 20/3
