A number divided by 61 give 27 as quotient and 32 as remainder. Find the number. 3. Find the largest number which divides 7 and 125 leaving remainder 5 and 8 respectively. 4. Can the number 6 n, where n being a natural number ends with digit 5? Give reason. Hint: 6 n = (2 3) n = 2 n 3 n, Clearly 5 is not a factor of 6 n. Therefore it can not end with digit Prove that is an irrational number. 6.
