7. thatiparthi : thanks for bringing in 83,I had marked equal bu just 23..

How did you zero in on 83?

my approach was to deduce that (n-5) was divisible by 6
and (n-3) was divisible by 5

then i tried it for 23.It never occured to me to try for different nos like 83

pls let me know your approach

apologies for not posting the qn first :

7. When ‘n’ is divided by 5, it gives remainder 3 and divided by 6, it gives remainder 5.
Col A: The value of ‘n’
Col B: 23
