Question

There are three numbers. The first number is the multiple of the second number. The second number is the 3rd multiple of the third number and if the third number is the 8th multiple of 752. Find the first number.

Answer 1

Let the first number be X

Then the second number is x+ 5

Then the third number is x+ 10

Now we are given that the sum of the three terms is 120.

==> x + x+ 5 + x+ 10 = 120

==> 3x + 15 = 120

Now we will subtract 15 .

==> 3x = 105

Now we will divide by 3.

==> x = 35

Then the numbers are: 35, 40...

Answer 2

Answer:

Step-by-step explanation:

Let the first number and the second number be F and S respectively.

5/2 F = 48/100 S —-> (1)

S = 1/9 * 1125 = 125

(1) => 5/7 F = 48/100 * 125

=> F = 84

25% of F = 1/4 * 84 = 21.
