7. Answer:

x = 4

Explanation:

Since the side of the square is x + 2, its perimeter = 4 (x + 2) = 4x + 8 Since the side of the equilateral triangle is 2x, its perimeter = 3 * 2x = 6x Also, the perimeters of both are equal.

(i.e.) 4x + 8 = 6x

(i.e.) 2x = 8 -> x = 4.

8. Answer:

5 (y – 2) / y.

Explanation:

To type a manuscript karthik took y hours.

Therefore his speed in typing = 1/y.

12. Answer:

Cost price of horse: Rs. 400 &

Cost price of cart: Rs. 200

Explanation:

Let x be the cost of horse & y be the cost of the cart. 10 % of loss in selling horse = 20 % of gain in selling the cart

Therefore (10 / 100) * x = (20 * 100) * y

x = 2y ———–(1)

5 % of loss in selling the horse is 10 more than the 5 % gain in selling the cart.

Therefore (5 / 100) * x – 10 = (5 / 100) * y

5x – 1000 = 5y

Substituting (1)

10y – 1000 = 5y

5y = 1000

y = 200

x = 400 from (1)

16. Answer:

30 days.

Explanation:

Before:

One day work = 1 / 20

One man’s one day work = 1 / ( 20 * 75)

Now:

No. Of workers = 50

One day work = 50 * 1 / ( 20 * 75)

The total no. of days required to complete the work = (75 * 20) / 50 =

30

17. Answer:

19. Answer:

250 lines of codes

20. Answer:

7 days

Explanation:

The equation portraying the given problem is:

10 * x – 2 * (30 – x) = 216 where x is the number of working days.

Solving this we get x = 23

Number of days he was absent was 7 (30-23) days.

21. Answer:

150 men.

Explanation:

One day’s work = 2 / (7 * 90)

One hour’s work = 2 / (7 * 90 * 8)

One man’s work = 2 / (7 * 90 * 8 * 75)

The remaining work (5/7) has to be completed within 60 days, because

the total number of days allotted for the project is 150 days.

So we get the equation

(2 * 10 * x * 60) / (7 * 90 * 8 * 75) = 5/7 where x is the number of

men working after the 90th day.

We get x = 225

Since we have 75 men already, it is enough to add only 150 men.

22. Answer:

(c) 1

Explanation:

a percent of b : (a/100) * b

b percent of a : (b/100) * a

a percent of b divided by b percent of a : ((a / 100 )*b) / (b/100) * a ))= 1

23. Answer:Cost price of horse = Rs. 400 & the cost price of cart = 200.

Explanation:-

Let x be the cost price of the horse and y be the cost price of the cart.

In the first sale there is no loss or profit. (i.e.) The loss obtained is equal to the

gain.

Therefore (10/100) * x = (20/100) * y

X = 2 * y —————–(1)

In the second sale, he lost Rs. 10. (i.e.) The loss is greater than the profit by

Rs. 10.

Therefore (5 / 100) * x = (5 / 100) * y + 10 ——-(2)

Substituting (1) in (2) we get

(10 / 100) * y = (5 / 100) * y + 10

(5 / 100) * y = 10

y = 200

From (1) 2 * 200 = x = 400

24. Answer:
