the eight number 5x32465y is divisible by 88.what is the value of 2x+3y

24,,sol. given no divisible by 88 so it also be div. by 11x8 ,,so by div. rule of 8 last three digit should be divisible by 8....then 65y/8 so take y=6 then digit totaly div. by 8 ..then by div. rule of 11 (sum of even digit =sum of odd digit),,,so, x+y+8=17,,.. x+y=9,,, put y=6...we find x=3 put these in 2x+3y and ans. is 24
