Question

Divide 36 into two parts in such a way that 1/5 od one part is equal to 1/7 of the other.
​

Answer 1

Answer:

there is one part 15 and 0ne is 21

Answer 2

Answer:

Let one part of 36 be x

So, Another part of 36 is (36-x)      {sum of 2 no.s is 36 }

Now we are given that that 1/5 of one part is equal to 1/7  of the other.

1/5x = 1(36-x) / 7

x/5   = 36/7-x/7

x/5 + x/7 = 36/7

12x / 35  = 36/5

    x     = (36/5)(35/12)

     x  = 15

another number = 36 -15 = 21

Hence the one part is 15 and another part is 21
