Question

If hundred cats kill hundred miles in hundred days, then four cats would kill for mice in how many days?

Answer 1

m1×d1×w2=m2×d2×w1

it's a formula to find the answer for your question.

m1=100

d1=100

w1=100

m2=4

d2=?

w2=4

here m refers to no. of cats killing the mice

d refers to the no. of days require to kill the mice

w refers to the work of killing the mice

therefore,100×100×4=4×d2×100

hence d2=100

100 days will be taken by 4 cats to kill 4 mice.
