(A) 44

(B) 45

(C) 66

(D) 77

Ans: C

Total marks obtained by the student = 55% of 800

= $$({55} / {100} × 800)$$ = 440.

∴ Marks scored in English = 15% of 440 = $$({15}/{100} × 440)$$ = 66.

(A) 30%

(B) 40%

(C) 60%

(D) 70%

Ans: C

Required percentage = $$({3%}/{5%} × 100)%$$

= $$[({3/100}) / ({5/100}) × 100]$$% = 60%.

Question: 3

In a college election between two candidates, one candidate got 55% of the total valid votes. 15% of the votes were invalid. If the total votes were 15200, what is the number of valid votes the other candidate got?

(A) 5814

(B) 6840

(C) 7106

(D) 8360

Ans: A

Number of valid votes

= (100 – 15)% of 15200 = 85% of 15200

= $$({85} / {100} × 15200)$$ = 12920.

Valid votes polled by other candidate

= (100 – 55)% of 12920 = $$({45} / {100} × 12920)$$ = 5814.

(C) 7868

(D) 7967

Ans: C

Number of students admitted in 2012

Ans: B

Given 30% of 1225 – 64% of 555 = ?

$$({30} / {100} × 1225)$$ - $$({64} / {100} × 555)$$
