If last three digits of N^3 is 888 then, what would be sum of digits of least value of N. Note Sum of digits of 128 = 11
a. 10
b. 11
c. 12
d. 16
approach plz @placiddisciple @sagarcat
If a = 4^1/3 [16^1/3 + 4^1/3 + 1], then find the value of a^3 - 12a^2 + 36a - 24.
6
12
0
18
Please give approach as well.
How many even numbers greater than 2000000 can be formed using the digits 0, 1, 1, 2, 3, 3, 5?
(a) 270 (b) 210 (c) 420 (d) 360
Find the value of 12 – 32 + 52 – 72 + …–1992.
(a) –20000 (b) –20400 (c) –19600 (d) 19800
plzz give d solution also
S1 = {2, 4, 6, 8, .................... 800}
S2 = {3, 6, 9, 12, .................. 900}
If S3 = S1 union S2, then what will be the 105th element of S3 if all its elements are arranged in
increasing order?
bhai koi bhi mock 7 ka ques no 8 samjha do..... kuch palle nahi pada.... n how to approach this types of question... 😠😠
Hi guys, i m in a crisis situation right now. Have a lot of doubts piled up in both quant & verbal, and since i m not a regular student of any coaching center, they refused to arrange any doubt sessions, could you please suggest a source from where i can get my doubts cleared. Please help. 😠😠

P.S- Don't know the OA. Approach would be appreciated.
For N
In a km race, if A gives B a head start 40m , then A wins by 19 sec, if A gives B a headstart of 30 sec , then B wins by 40m. Find the time taken by each to finish the race.
Ans (125s, 150s)
Please share the approach, i tried solving the way i know but i'm getting wrong answer. So please explain it as well.
Thanks
