percentage Model Questions & Answers, Practice Test for ssc cgl tier 1 2024

Answer: (a)

Let the number be x.

then, $x × 15/100 × 45/100$ = 105.3

$x = {105.3 × 100 ×100}/{15 × 45}$ = 1560

So, 24% of 1560 = 374.4

Answer: (c)

$(250 × 18/100 + 144 × 25/100)$ of ? = 54

(45 + 36) of ? = 54

81 × ? = 54

? = $54/81 = 2/3$

Answer: (c)

Let maximum marks of test = x

Vidya marks = 350 + 296 = 646 = 76% of x

$x = {646 × 100}/76$ = 850

Answer: (a)

? = ${599 × 65}/100$ = 389.35

Answer: (d)

Total marks = 180 + 150 = 330

Student gets 30% in 1st paper out of 180 and gets at least 50% marks overall.

i.e., $330 × 50/100 = 165$ marks overall.

Let he scores x marks out of 150 in IInd paper.

∴ According to the question :

$165 - 180 × 30/100 = x$

x = 111marks.

Thus, $111/150 × 100$ = 74% marks

∴ He should get 74% marks in IInd paper.
