four numbers add up to 95. The second number is twice the first number, the third number is three times the first number and the fourth number is 25 more then the first number. what are the four numbers?
let numbers are A B C D
as per given conditions
B=2A (1)
C =3A (2)
D =A +25 (3)
A + B + C + D =95 by substitution
A + 2A + 3A + A + 25 =95
7A + 25 = 95
7A = 95-25 =70
A =70/7
A =10
Answer
first number =10
second number= 20
third number =30
fourth number = 35
verification 10+20+30+35 = 95 verified
