375 ml of mixture contains milk and water in the ratio of 16 : 9 respectively. If x ml of water is added into the mixture then the ratio of milk to water in the resultant mixture becomes 3 : 2, find the value x.

30

25

40

45

Option B Quantity of milk = 375 * 16/25 = 240 quantity of water = 375 * 9/25 = 135 ATQ, 240/135 + x = 3/2 3x + 405 = 480 x = 25

A and B alone can complete a piece of work in 24 days and 20 days respectively. If efficiency of C is 60% more than A, then find in how many days C complete the work ?

15 days

17 days

20 days

25 days

30 days

Option A LCM of 24 and 20 = 120 efficiency of A = 120/24 = 5 efficiency of B = 120/20 = 6 efficiency of C = 5 * 160/100 = 8 time required = 120/8 = 15 days

A shopkeeper marked up an article 25% above its cost price and allowed a discount of 40% on it. If shopkeeper made a loss of rs.128, then find what is the cost price ?

620

340

580

512

480

Option D Let CP of article = 100x MP of article = 100x * 125/100 = 125x SP of article = 125x * 60/100 = 75x loss = 100x – 75x = 25x CP of article = 128/25x * 100x = 512

P and Q started a partnership business with investment of rs.15000 and rs.12000 for 8 months and 6 months respectively. If total profit of the business is 6400, then what is profit share of P ?

3200

4450

3800

4200

4000

Option E Profit sharing ratio of P and Q = 15000 * 8 : 12000 * 6 = 5 : 3 profit share of P = 6400 * 5/8 = 4000

A man invested rs. 25000 at the rate of 20% in compound interest for 1 year. How much amount he received if he invested for compounded half yearly.

42000

22000

30250

28140

34400

Option C Rate of compound interest for half yearly = 20/2 = 10% rate of CI after 1 year = 10 + 10 + 10 * 10/100 = 21% CI = 25000 * 21/100 = 5250 amount = 25000 + 5250 = 30250

Directions : What will come in place of questions mark in the following questions given below ? 20^2 + 328 – 84 = 28% of 300 + ?

Thanks for your fascinating article. One other problem is that mesothelioma is generally a result of the inhalation of fibers from asbestos fiber, which is a positivelly dangerous material. Its commonly seen among personnel in the engineering industry that have long contact with asbestos. It can also be caused by living in asbestos protected buildings for a long period of time, Genetic makeup plays an important role, and some people are more vulnerable towards the risk in comparison with others.
