10. How many two digit numbers are divisible by 13?

Answer 1

THE FIRST TWO DIGIT NUMBER DIVISIBLE BY 13 IS 13 AND LAST TWO DIGIT NUMBER DIVISIBLE BY 13 IS 91

SO a=13 d=13 tn= 91

tn = a+(n-1)*d
tn = 13+(13n-13)
91 = 13n
n = 7

Question :-

☆ How many two digit numbers are divisible by 13?

Solution :-

☆ 7*13 is 91, there are no two digit numbers larger than this that are multiples of 13. So there are 7 positive two digit integers that are divisible by 13 without leaving a remainder. But equally, -1 times 13 is -13, and that's a two digit number.
