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

Answer: (a)

$? = (383 × 739/100) ÷ 628$

$≈ ({380 × 740}/100) ÷ 630 ≈ 2812 ÷ 630 ≈4.46 ≈4.50$

Answer: (c)

64.5% of 800 + 36.4% of 1500 = $(?)^2$ + 38

516 + 546 = $(?)^2$ + 38

1062 – 38 = $(?)^2$

1024 = $(?)^2$

$(32)^2 = (?)^2$

? = 32

Answer: (c)

Percentage savings of Mr.Davar

= 100 – (38 + 25 + 12) = 25%

Let his monthly income be x

25% of x = 5800

$x = 5800 × 100/25 = 23,200$

Answer: (b)

Total increase = 20 + 20 + ${20 × 20}/100$ = 44%

∴ Reduce in number = $44/144 × 100 = 30{5}/9$ %

According to the question,

$x/8 = 17.25$

or x = 17.25 × 8 = 138

73% of 138 = $138 × 73/100$ = 100.74
