I dont understand why it's 7*6 @AkashdeepDeb

how do i even know what 7*6 calculates

not sure

hmmmmm.... trying to process this in my head

60*x / 120

can i do proportions with this?

ok got it i think

did u want some help with this, you bumped it up?

do u have a different interpretation?

well there was a great trick suggested already

why is it 7*6

it doesnt have to it, this relation just exists between the 7 and 4 and the number of hours

yes

7 pumps take 6 hours to complete this work,, which means each pump worked for 6 hours

7 of these pumps worked for 6 hours in total

yes

yea

okay so

now when its 4 pumps, that means we have to work 7/4 times more xD

yea

so 7/4 * 6 is our hours,

hmmmm i see

so it's proportions?

here is another way that 7*6 = 4*h relationship comes up

i forgot what i was about to say xD

lol

does that make sense to you?

kinda...

okay i think i got it... thanks guys

no problem there are many ways to solve a problem just use the easiest for you!
