Question

. Which is greater, the sum of 16.93 and 23.623 or the difference of 68.550 and 20.8; and by how much?

Answer 1

Answer:

let the two numbers beA and B

so it is given that

A+B=25...(1)

A−B=7 ...(2)

Adding the equations we get

A+B+A−B=25+7

2A=32

A=16

Using the above value of A in (1)

So 16+B=25

=>B=9

Thus A=16 and B=9
