Question

find the least number when divided by 12 ,leaves a remainder of 7,when divided 15 ,leaves a remainder of 10 and when divided by 16 leaves a remainder of 11.
pls answer fast friends.
atleast give steps

Answer 1

when divided by 12 ,leaves a remainder of 7
difference = 12 - 7 = 5
when divided by 15 ,leaves a remainder of 10
difference = 15 - 10 = 5
when divided by 16 ,leaves a remainder of 11
difference = 16 - 11 = 5

LCM(12,15,16) = 240
so required number is 240 - 5 = 235

Answer 2

first 12 leaves,remainder 7.So simple.12-7=5
it is the difference.
Then,
15 leaves,remainder of 10.
Again subtract it,15-10=5(5=difference)
16-11=5
