Question

5 purush ya 15 bacche kisi karya ko 30 din mein karte hain to usi karya ko 5 purush aur 6 mahilayen milkar kitne din mein pura karenge yadi do bacche barabar ek mahila ho to?

Answer 1

Step-by-step explanation:

do bacche barabar ek mahila,

2B = 1F

5 purush aur 6 mahilayen = 5 purush aur 12 bacche

5M + 6F is converted into 5M + 12 boys

5 purush ya 15 bacche kisi karya ko 30 din mein karte hain to usi karya ko 5 purush aur 6 mahilayen milkar kitne din mein pura karenge

required number of days ,

= given days/ (aur/ya)+(aur/ya)

= 30 / (5/5)+(15/12)

= 30/(9/4)

= 120/9

= 40/3

= 13 1/3 days
