Question

The product of two numbers is 18.75. If one number is 7.5 which is thrice
of another .Find the smaller number

Answer 1

Answer:

Define x.

Let one of the number be x

The other number is 3x

Solve x:

The product of two numbers is 18.75

x(3x) = 18.75

3x sq2 = 18.75

x sq2 = sq root6.25

x = 6.25

x = 2.5

Find the numbers:

one of the number = x = 2.5

the other number is 3x = 3(2.5)=7.5

The greater number is 7.5

Answer 2

Answer:

product of two no. = 18.75

one no. = 7.5

let, other no. be x

A/q

7.5 × x = 18.75

=> x = 18.75/7.5

=> x = 2.5

therefore, 2.5 is the other no.
