Let the three consecutive multiples of 8 be x,x+8 and x+16.
According to question, x+x+8+x+16=888
⇒ 3x+24=888
⇒ 3x+24-24=888-24 [Subtracting 24 from both sides]
⇒ 3x=864
⇒ 3x/3 = 864/3
⇒ x=288
Hence, first multiple of 8 = 288, second multiple of 8 = 288 + 8 = 296 and third multiple of 8 = 288 + 16 = 304.
