Answer 1

let the first no. be x. Second no. be y.

Answer 2

Answer:

121

Step-by-step explanation:

Let the first number be x and the second number be y.

From the information above :

6/11x = 22/100y

The second number y is 1/4 of the third number.

The third number = 2400 therefore y is :

y = 1/4 × 2400 = 600

y = 600

From the relationship between x and y we can get x

6/11x = 22/100 × 600

6/11x = 132

x = 132 × 11/6 = 242

The first number is therefore 242.

We need 50% of the the first number.

This equals to :

50/100 × 242 = 121
