Answers :

Directions (1-5) :

1) Answer: D

A&C in 2017 = 35% 11400 = 3990

B, C, F in 2018 = 32% 16800 = 5376

Diff = 1386

2) Answer: C

36% of 11400 = 4104

No. of valid app = 11400 – 4104 = 7296

Total no. of app from D = 35% of 11400 = 3990

Total no. of valid app from D = 3990 – 194 = 3796

3796 / 7296 * 100 = 52.02%

3) Answer: B

30% of 11400 = 3420

3420 + 420 = 3840 – – – 1

55% of 16800 = 9240

9240 + 420 = 9660 – – – 2

Now, 3840: 9660 = 64: 161

4) Answer: D

80% of 35% of 11400 – 60% of 15% of 11400

3192 – 1026 = 2166

5) Answer: C

25% of 16% of 16800 + 35% of 25% of 16800 + 27% of 16800

672 + 1470 + 4536 = 6678
