Answer:
Three consecutive integers are 7,8 and 9
Solution:
Let the numbers are x, x+1 and x+2
(Since these are consecutive integers)
they are taken in increasing order and multiplied by 2,3 and 4 respectively
So x becomes 2x
(x+1) becomes 3(x+1)
(x+2) becomes 4(x+2)
they add up to 74,so ATQ
2x + 3(x + 1) + 4(x + 2) = 74
2x + 3x + 3 + 4x + 8 = 74
9x + 11 = 74
9x = 74 - 11
9x = 63
x = 63/9
x = 7
So,
Integers are 7,8,9
Verification:
2 x 7+3 x 8+4 x 9
=> 14+ 24 + 36
=> 74
Hence the calculate integers are correct.
