Question : Directions: Study the following bar diagram carefully and answer the questions. The bar graph given below shows the foreign exchange reserves of a country (in millions US $) from 1991-1992 to 1998-1999.
The ratio of the number of years, in which the foreign exchange reserves are above the average reserves, to those in which the reserves are below the average reserves is:
Option 1: 2 : 6
Option 2: 3 : 4
Option 3: 3 : 5
Option 4: 4 : 4
Correct Answer: 3 : 5
Solution : Average of the foreign exchange reserves of a country (in millions USD) from 1991-1992 to 1998-1999 is: $=\frac{2640+3720+2520+3360+3120+4320+5040+3120}{8}$ = 3480 The number of years in which the reserves are above the average reserves = 3 The number of years in which the reserves

Question : Roma spends 25% of her income on food, 15% on children's books and 75% of the remaining income on uniforms. What is the percentage of income she is left with?
Option 1: 35%
Option 2: 20%
Option 3: 15%
Option 4: 19%
Correct Answer: 15%
Solution : Let the income be 100. Spent on food = 25% Spent on children book = 15% Remaining salary = 100 – 25 – 15 = 60% 75% of the remaining on uniform = $\frac{75}{100}\times60=45$ $\therefore$ She left with 60 – 45 = 15% Hence, the
Question : If $a+b-c=20$ and $a^2+b^2+c^2=152$, find the value of $a^3+b^3-c^3+3abc$.
Option 1: 480
Option 2: 720
Option 3: 640
Option 4: 560
Correct Answer: 560
Solution : Given: $a+b-c=20$ and $a^2+b^2+c^2=152$ $ a+b-c = 20$ Squaring both sides, we get, ⇒ $a^2 + b^2+c^2 + 2ab-2bc-2ca = 400$ ⇒ $2(ab-bc-ca) = 400-152$ ⇒ $ab-bc-ca = 124$ Now to find, $a^3+b^3-c^3+3abc$ $= (a+b-c)(a^2+b^2+c^2-(ab-bc-ca))$ $= 20\times (152-124)$ $= 20\times 28 = 560$ Hence, the
Question : Directions: In the following question, some parts of the sentence have errors, and some are correct. Find out which part of the sentence has an error. The number of that part is the answer. If a sentence is error-free, your answer is "No Error."
