b.... 2month and 9 days. % operator is used to find the remainder wen two num are divided... here num=69 wen divided by 30 will yield 9 as remainder. hemce days=num%30=9 69/30 will give 2 as result since this is integral division.... hence month =2 ...

Ans is B.
Here the num stores 69 and we are calculating days using modulo(%) operator on num by 30 which store 9 in 'days' varaible(days = num % 30 = 69 % 30 = 9) and we are calculating months using division(/) operator on num by 30 which stores 2 in 'months' variable(months = num / 30 = 69 / 30 = 2)... which results the output as 2 months and 9 days....

ans b . modulus operator, % returns the remainder of a division operation.  when we divide 69(dividend) with 30(divisor) then the quotient is 2 and the modulus (or remainder) is dividend is sum which is 69, thn remainder assigned with days=9.thn month is assigned with quotient which has value 2.finally sop prints 2 Months and 9 days
