I. X = Rs. 7821414

II. The man invested @ of 10% per annum simple interest.

1.3

Number of items produced by company C3 = 72/360 * 160000 = 32000

Total cost of production = 32000 * 8000 = Rs. 256000000

Cost of production of product B = 3/5 * 256000000 = Rs. 153600000

Profit percent earned on product B by company C3 = 12/100 * 153600000 = Rs. 184.32 lakh

2. 4

Cost of production of product A by company C4 = 108/360 * 160000 * 8000 * 1/3 = Rs. 1280 lakh

Cost of production of product A by company C5 = 90/360 * 160000 * 8000 * 2/5 = Rs. 1280 lakh

3. 1

Total profit = [ 36/360 * 4/5 * 30/100 + 54/360 * 2/5 * 25/100] * 160000 * 8000

= (0.024 + 0.015) * 160000 * 8000 = Rs. 4.992 crore

4. 2

Required ratio = 90/360 * 3/5 : 36/360 * 4/5 = 15 : 8

5. 1

Required percentage = (72 * 3/5) / (90 * 2/5) * 100 = 120%

6. 3

Let the cost of a T.V. be Rs. x, the cost of a music system

be Rs. y, the cost of a microwave be Rs. p and the cost of a fridge be Rs. q.

From statement I;

0.35x + 0.25 y > 0.45 p + 0.65 q

x + 5/7 y > 9p/7 + 13q/7

The sum of the cost of TV and music system must be more than the sum of a microwave and fridge.

Hence, statement I alone is sufficient to answer the question.

From statement II,

0.25x + 0.35y < 0.15p + 0.20q

X + 7y/5 < 3p/5 + 4q/5

From this statement we conclude that the cost of a microwave and fridge is more than the cost of a t.v. and a fridge.

Hence, statement II alone is sufficient to answer the

question.

7. 4

Since, sales do not indicate anything about the profit, we cannot get answer from I alone.

Now, from statement II;

Let the profit in 2013 and 2014 be Rs. x and Rs. y respectively.

y = 1.35 {(x+y)/2}

2y = 1.35x + 1.35 y

y = 27/13x

No, the profit in 2013 is not more than the profit in 2014.

8. 5

From statement I, down payment is not known, so we cannot find the price of truck.

From statement II and I together,

Let the down payment be Rs. d then,

x = d + 31784 × 50 (where x is the total cost of truck)

x = 37/100 x + 1589200

x = 158920000/63 = 2522540

9. 3

From statement I:

x^3 + y^3 + z^3 = 3xyz

(x^3 + y^3 + z^3)/xyz = 3

So, statement I is sufficient.

From statement II:

(x^3 + y^3 + z^3)/xyz = (1 + 8 + 27)/6 = 6

So, statement II alone is sufficient to answer the question.

10. 2

From statement II;

If a, b and c are the sums divided to Anu, Bharti and Divya respectively. Then,

or 15 a = 16b = 17c = k

a : b : c = 16 × 17 : 15 × 17 : 15× 16 = 272 : 255 : 240
