Question : Directions: A watch company produces four different products. The sale of these products in lakhs during 2005 and 2010 is shown in the following bar diagram. Study the graph and answer the question.
The sales of table clocks in 2010 were less than the sales of wall clocks in 2010 nearly by:
Option 1: 70.5%
Option 2: 69.05%
Option 3: 68.05%
Option 4: 62.05%
Correct Answer: 69.05%
Solution : As per the given graph, The sales of table clocks in 2010 = 9.5 lakh The sales of wall clocks in 2010 = 30.7 lakh The required percentage = $\frac{30.7-9.5}{30.7}$ × 100 = $\frac{21.2}{30.7}$ × 100 = 69.05% Hence, the correct answer is 69.05%.
Question : An electronic store owner allows two successive discounts of 20% and 25% on each item. The store has a reward points scheme that enables a customer to get free shopping worth INR 0.10 on every 1 reward point credited to the customer's account on previous purchases from the store.

Question : Find the LCM of $\frac{3}{2}, \frac{81}{16}$ and $\frac{9}{8}$
Option 1: $\frac{91}{2}$
Option 2: $\frac{81}{2}$
Option 3: $\frac{111}{2}$
Option 4: $\frac{101}{2}$
Correct Answer: $\frac{81}{2}$
Solution : Given fractions = $\frac{3}{2}, \frac{81}{16}$ and $\frac{9}{8}$ We know that, LCM of a fraction = $\frac{\text{LCM of the numerators}}{\text{HCF of the denominators}}$ LCM of 3, 81, 9 is 81. HCF of 2, 16 and 8 is 2. $\therefore$ LCM of $\frac{3}{2}, \frac{81}{16}$ and $\frac{9}{8}$ =
Question : Find the Simple Interest on INR 27,000 at $14 \frac{2}{3}$% per annum for 8 months.
Option 1: INR 2,600
Option 2: INR 2,630
Option 3: INR 2,610
Option 4: INR 2,640
Correct Answer: INR 2,640
Solution : Given: Principal = INR 27,000 Rate of interest = $14 \frac{2}{3}$% Time period = 8 months = $\frac{8}{12}=\frac{2}{3}$ year. Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$ = $\frac{27000×\frac{44}{3}×\frac{2}{3}}{100}$ = 60 × 44 = INR 2,640. Hence, the correct answer is INR 2,640.
Question : Directions: In a certain code language, FALF is written as HCJD. How will OEMC be written in that language?
Option 1: QGAK
Option 2: QGKA
Option 3: QKAG
Option 4: QKGA
Correct Answer: QGKA
Solution : Given: FALF is written as HCJD.
Add 2 to the place value of the first two letters and subtract 2 from the place value of the last two letters of FALF to get the required code.
So, FALF is written as HCJD. Similarly, follow the
Question : Directions: In a row, Sanjay is in 11th position from the top and 13th from the bottom. How many people are there in the row?
