HEY THERE!
I HAVE ANSWERED THIS
https://brainly.in/question/1152794
This question can be solved by binomial co-efficients
we know Ncr =n!/r! (n-r)!
5!=120
3! =6
2!=2
So 5c3 =5! /3!(5-3)!
120/6*2!
120/6*2
120/12
10
Finally
15+5+ [ 5C 3]=30
15+5+10=30
hence proved
It is so easy
Hope helped!!

[ ] + [ ] + [ ] = 30
No. we can use is = 1,3,5,7,9,11,13,15
Sol.
= 11 + 3! + 13
= 11 + (1 * 2 * 3) + 13
= 11 + 6 + 13
= 17 + 13
= 30.... Hence Solved
Hope It Helps You :)

I know
in the 1st box used tHat is combination
old symbol
we can write Ncr like that in brackets
please ask any of the teachers who teach IAS persons
yes
my teacher guided me....and i did this ...it is 100% correct
ur also correct
in IAS exams there is no restrictions to use any symbol....got it
all questions are based on sequence....and permutations and combination are the basics rule we can apply it any where

I solved the question bank of upse so it is the reasoning one...
here we have to use factorial...
like 3 ! = 3×2×1 = 6
4 ! = 4×3×2×1 = 24.
similarly...
