 Question Answer 1. b 2. d 3. a 4. b 5. d 6. c 7. c 8. d 9. b 10. a

Explanation: 1. Assuming, Machine A produces 100 units in a certain time   period.

Machine B would produce 6 times of X or 600 units.

Machine C would produce half of that = 300 units

The three machines together would produce 1000 units, of which 300 are produced by machine C.

Required Fraction = 300/1000= 3/10

Explanation: 2. Explanation: 3. Explanation: 4. Ratio of A, B and C.

A: B: C = (50000 X 12 + 70000 X 12 + 70000 X 12) : (70000 X 12 + 90000 ×12) : (70000 X 12)

= 2280000: 1920000: 840000 =19: 16: 7

A’s share = Rs. (2, 10,000 × 19/42) = Rs. 95,000

Explanation: 5. Both the states have an equal number of candidates appeared then difference = (10% – 8%) = 120

1% = 60 and 100% (total number of candidates appeared) = 6000

Explanation: 6. Let x be no. of women and y be no. of men.

Then no. of handshakes = x*y = 24.

Then factors of 24 are (6,4);(8,3);(12,2).

Thus x or y = 6 and y or x = 4, it is immaterial for present answer.

Next, no. of hugs is given by XC2 + YC2 (easy if you remember that only 02 women/men hug at a time within their 2 groups).

Then start placing the 3 groups of factors. We find that for first, number of hugs is 21; for second 68; for third 31.

Only 21 is given in answer

Explanation: 7. Let ABCD be the given parallelogram measuring 5 cm and 3.5 cm. One of its diagonals measures 6.5 cm, as shown in the figure. We know that the diagonal AC of the parallelogram divides it into two triangles of equal area.

Area of parallelogram ABCD = 2 X area of triangle ABC

Now, we calculate area of ΔABC . Explanation: 8. Area of the quadrilateral ABCD = Area of + Area of the ΔADC as shown in the figure. Study the following graph carefully and answer the questions given below it.

A district showing employment data (total population = 36000) L-employed Literate unemployed Illiterate-employed Illiterate-unemployed Urban Rural Urban Rural Urban Rural Urban Rural 80% 20% 30% 70% 80% 20% 20% 80%

Explanation: 9. Required ratio =  9/360× 36000 × 80/100 : 50/360 × 36000 × 20/100 = 36:5

Explanation: 10. Required amount = (90/360× 36000 × 80/100)/(90/360 × 36000 × 20/100) = 4
