1.

N is the largest two digit number, which when divided by 3, 4 and 6 leaves the remainder 1, 2 and 4 respectively. What is the remainder when N is divided by 7?

Answer»

Answer:

TRIAL and error soon determines that the smallest such number is 10

The LCM of 3, 4 and 6 is 12.

So, find the largest multiple of 12 that is still under 100 when you ADD 10 to it.

84 + 10 = 94

94 MOD 5 = 4
