6. A contractor agreeing to finish a work in 150 days, employed 75 men each working 8 hours daily. After 90 days, only 2/7 of the work was completed. Increasing the number of men by ________ each working now for 10 hours daily, the work can be completed in time.
a)145men
b)100men
c)150 men.
d)125men
The Correct Answer is:
c)150men
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.

8. A man bought a horse and a cart. If he sold the horse at 10 % loss and the cart at 20 %
gain, he would not lose anything; but if he sold the horse at 5% loss and the cart at 5% gain,
he would lose Rs. 10 in the bargain. The amount paid by him was Rs._______ for the horse
and Rs.________ for the cart.
a)600,400
b)400,200
c)800,300
d)100,200
The Correct Answer is:
b)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
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
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
