If a machine consumes (k)/(5) kilowatts ...

If a machine consumes `(k)/(5)` kilowatts of power every t hours, how much power in kilowatts, will three such machines consume in 10 hours ?

A

`k/t`

B

`(6t)/k`

C

`(6k)/t`

D

`t/k`

Text Solution

Verified by Experts

The correct Answer is:
C
`because` t घंटे `k/5` में बिजली खपत होती है।
`therefore` 1 घंटे में `k/(5t)` बिजली खपत होती है।
`therefore` 10 घंटे में `(kxx10)/(5t)` बिजली खपत होती है।
= `(2k)/t`
`therefore` तीन मशीन में कुल बिजली की खपत = `(2k)/txx3=(6k)/t`
