How comparable are crackus mocks/ sectionals with the real cat?

Full Mocks are of the same level. LRDI sectionals are a tad difficult than actual CAT whereas Quant mocks are easier than CAT. Verbal Sectionals are of the same level. This is what I feel.

I feel mocks are at same level but sectionals are easy.

In many mocks like Dashcat 5 lrdi,there is not any video solution but option of liking or disliking video is available.Why is it so?

Yes problem solved,no issue now.

what is the sum of digits of the least number which when divided by 15 18 24 leaves a remainder 8 in each case and also divided by 13

LCM of 15,18, 24 = 360 So the number is of the form 360k+8 This number is also divisible by 13. When k=1 i.e. 368 is not divisible by 13 When k=2 i.e. 728 is divisible by 13. Hence 728 is the answer!
