Answer 2

The given question is 75% of a number exceeds 65% of that number by 80.

Do we have to find what is twice that number?

The given options are

a)800

b)1000

c)1200

d) 1600

let the number be y.

75% of the number exceeds 65% of the number by 80.

75% can be written as 0.75

65% can be written as 0.65

The expression based on the above question is

$0.75y - 0.65y = 80$

The subtraction value will be

$(0.75 - 0.65)y = 80 \\ 0.1y = 80$

The value y will be the division of

$80 \: and \: 0.1$

$y = \frac{80}{0.1}$

Therefore, the value of y will be 800.

we have to find twice that number.

The twice that number

$2y = 800 \\ 2(800) = 1600$

The given value was twice that number

Therefore, the correct option for the given question is

d.
