Let the consecutive multiples be 8x,8(x+1), 8(x+2) According to question, 8x+8(x+1)+8(x+2)=888 8x+8x+8+8x+16=888 24x+24=888 24x=888-24=864 x=864/24=36 So,all multiples are36,37,38.

Dilip Kumar 7 years, 1 month ago

According to the question, The three consecutive number=x , x+1 , x+2. The sum of 3 consecutive multiples of 8 = 8(x+x+1+x+2) First multiple =8x Second multiple = 8(x+1) Third multiple=8(x+2) =8x+8x+8+8x+16 Now , the expression is 8x+8x+8+8x+16=888 24x+24=888 24x=888-24 24x=864 x=864/24 Hence , x=36 First multiple = 8x = 8×36 = 288. Second multiple = 8(x+1)=8×(36+1)=8×37=296. Third multiple = 8(x+2)=8×(36+2)=8×38=304. Hence , the multiples are 288 , 296 , 304 .
