**10.** The cost of 87 pens and 29 pencils is Rs. 783. What is the cost of 90 pens and 30 pencils?

1) Rs. 804 2) Rs. 810 3) Rs. 816 4) Rs. 824 5) Rs. 830

**Explanations**

∴ Male_{A} = 504

Similarly, for other companies we get total

Females = 1796

And total males = 2204

∴ Diff = 408

**3.** 2; Male (A + B + C) = 504 + 517 + 356 = 1377

Female (D + E + F) = 192 + 122 + 407 = 721

∴ Diff = 1377 – 721 = 656

**5.** 4; Female_{B} = 423 Male_{F} = 333

**6.** 1; Let the present age of the father be

X and that of the son be y. Then =

∴ 3x = 8y ……..(i)

Further, = ∴ x + 12 = 12y + 24

∴ x- 2y = 12 …..(ii)

From eqn (i) and (ii), x = 48, y = 18

∴ Sum = 66 yrs.

7. 2; Probability of these being all men in the committee is =

∴ Probability of these being at latest one

**8.** 2; 25 men – 24 days – 1 work

**9.** 3; Let the length be x and breadth be y.

X = y + 72 ∴ 13y = 9y + 648

∴ x = 162 + 72 = 234

∴ Perimeter = 2(234 + 162) = 2 x 396

= 792 ft

**10.** 2; Let the price of a pen be x and that of pencil be y.

Then 87x + 29y = 783 ……..(i)

Multiplying eqn (i) by = 783 x

∴ 90x + 30y = 810
