Question

Find four numbers whose sum is 45, If the first number +2=second number -2=Third number*2=Fourth number ÷ 2.

Answer 1

Answer:

a=8,b=12,c=5,d=20

Step-by-step explanation:

let a,b,c,d are the numbers.

a+b+c+d = 45

a+2 = b-2 = c*2 = d÷2 = k (say)

a=k-2

b=k+2

c=k/2

d=2k

(k-2)+(k+2)+k/2 + 2k = 45

4k + k/2 = 45

9k/2 = 45

k = 10

a=8,b=12,c=5,d=20

Answer 2

Answer:

13 +15+7+10 =45

so, 13+2 = 15

• 15-2= 14
• 7 *2=14
• 10/2= 5
