Direction: Study the line graph carefully to answer the following questions.
Line graph shows the production (in thousand units) and percentage of exported mobiles, computers and laptops.

Find the total number of Mobiles, Computers and Laptops exported in the year 2011. 

Direction: Each of the questions consists of a question and two statements numbered I and II given below it. You have to decide whether the data provide in the statements are sufficient to answer the question. Read both the statements and Give answer.
(A) If the data in statement I alone are sufficient to answer the question, while the data in statement II alone not sufficient to answer the question;
(B) If the data in statement II alone are sufficient to answer the question, while the data in statement I all are not sufficient to answer the question;
(C) If the data either in statement I alone or in statement II alone are sufficient to answer the question;
(D) If the data even in both statements I and II together are not sufficient to answer the question;
(E) If the data in both statements I and II together are necessary to answer the question.

A and B together can do a piece of work in 16 days and B and C together can do the same work in 24 days. From starting A and B worked for 4 days and 7 days respectively, when A lefts the work then C joins the work and he works for 23 days and complete the work. Then find in how many days will C complete the work alone?

Two circles of radii 4 cm and 9 cm respectively touch each other externally at a point and a common tangent touch them at the points P and Q respectively. Then the area of square with one side PQ, is:

The value of   $${(75.8)^2-(55.8)^2\over20}$$

The maximum number of common tangents drawn to two circles when both the circles touch each other externally is 

$$ {3sin60°-4sin^{3}60°=?}$$
