Question

ram thought of a number and then double it. After subtracting 5 from the result, he multiplied it by 5. if the product is 105, what was the number ram thought of?

Answer 1

LEt ,

The number be x

If we double it =2x

And subtract 5=2x-5

And multiply by 5=5(2x-5)

=10x-25

The product is 105

Hence, 10x-25=105

10x=105+25

10x=130

x=130/10

X=13

Hence the number be 13
