The sum of three numbers is 280. If the ratio between the first and second number is 2:3 and the ratio between second and third number is 4:5, then find the second number.

• SOLUTION

let three numbers be X Y Z

sum of three numbers as per question X+Y+Z = 280

NOTE WHEN ONLY TWO VALUE ARE GIVEN REPEAT THE VALUE AGAIN AS DONE ABOVE

sum of three numbers as per question 8+12+15 = 35

MEANS 35 represents 280

1 represents 280/35= 8

in question they asked to find the second number with is 12, so 12×8 =96

ANSWER 96
