Let S 1 = 
10 C j , S 2 = 
10 C j and S 3 = 
10 C j .
Statement -1 : S 3 = 55 × 2 9 .
Statement -2 : S 1 = 90 × 2 8 and S 2 = 10 × 2 8 .
Text Solution
Verified by ExpertsThe correct answer is:
B
S 1 = 
8 C j–2
⇒ S 1 = 9 × 10 
⇒ S 1 = 90 . 2 8
S 2 = 
–1 = 10.2 9
S 3 = 
= 
= 90 
= 90 × 2 8 + 10 × 
2 9 = (45 + 10) . 2 9 = (45 + 10) . 2 9 = 55.2 9
so statement-1 is true and statement 2 is false.
