Answers:

1. Answer: (c)

Marked price of each item = 500

No. of items = 5

Total marked price = 500 × 5 = 2500

Total discount =2x500x8/100+3x500x16/100=320

Effective discount=320/2500×100= 12.8%

2. Answer: (d)

Mean of marks of the students (60 +64+ 40+ 60 +60+ 58)/ 160  = 9720/160= 60.75

3. Answer: (b)

Let the price of the article = ` 100

New Price = 100 – 33 = 67

Therefore the new price must be increased by (100 -67 )x100 /67= 3300 /67= 49.25%

4. Answer: (a)

Here, Total surface area of hemisphere = 166.32 sq cm.

r =?

3 x 22/7 x r²=166.32

r²=17.64

r = 4.2 cm.

5. Answer: (b)

Net effect = – 20 + 80 + (–20 80) /100 = 60 – 16 = 44%

6. Answer: (c)

Total score of 40 innings = 40 × 50 = 2000

Total score of 38 innings = 38 × 48 = 1824

Let the highest score be x and the lowest score be y.

Sum of the highest and the lowest score = x + y = 2000 – 1824 => x + y = 176 …(i)

and by question, x – y = 172 …(ii)

Solving (i) and (ii), we get x = 174

7. Answer: (c)

2 + 4 = 6

6 + 5 = 11

11 + 6 = 17

17 + 7 = 24

24 + 8 = 32

8. Answer: (d)

If the first divisor be a multiple of the second divisor, then required remainder = remainder obtained by dividing the first remainder (36) by the second divisor (17) = 2 Q 17 is a factor of 136 \ Remainder when 36 is divided by 17 = 2

9. Answer: (b)
