Question : A shopkeeper sells an article at $13 \frac{1}{2}\%$ loss. If he sells it for INR 1,274 more, then he gains $11\%$. What is the cost price of the article?
Option 1: INR 4,874
Option 2: INR 4,800
Option 3: INR 5,200
Option 4: INR 5,274
Correct Answer: INR 5,200
Solution : Let the cost price be INR $x$. Selling price at a $13 \frac{1}{2}\%$ loss $=(\frac{100-\frac{27}{2}}{100})x=\frac{173x}{200}$ According to the question, $\frac{173x}{200}+1274=\frac{100+11}{100}x$ $⇒\frac{111x}{100}-\frac{173x}{200}=1274$ $⇒\frac{49x}{200}=1274$ $\therefore x =5200$ Hence, the correct answer is INR 5,200.
Question : Directions: If EARTHQUAKE is coded as EKAUQHTRAE, then ELECTORATE will be coded as?
Option 1: ETAROELECT
Option 2: EARTOTCELE
Option 3: ETAROTCELE
Option 4: ETAROCTELE
Correct Answer: ETAROTCELE
Solution : Given: EARTHQUAKE is written as EKAUQHTRAE.
EARTHQUAKE is written as EKAUQHTRAE – After reversing the letters of the word EARTHQUAKE→EKAUQHTRAE Similarly, reverse the letters of the word ELECTORATE→ETAROTCELE
So, the code for ELECTORATE is ETAROTCELE. Hence, the third option is correct.
Question : In a triangle ABC a straight line parallel to BC intersects AB and AC at D and E, respectively. If AB = 2AD, then DE : BC is:
Option 1: 2 : 3
Option 2: 2 : 1
Option 3: 1 : 2
Option 4: 1 : 3
Correct Answer: 1 : 2
Solution : AB = 2AD As $\triangle$ADE ~ $\triangle$ABC, ⇒ $\frac{\text{AD}}{\text{AB}}$ = $\frac{\text{DE}}{\text{BC}}$ ⇒ $\frac{1}{2}$ = $\frac{\text{DE}}{\text{BC}}$ ⇒ $\frac{\text{DE}}{\text{BC}}$ = $\frac{1}{2}$ Hence, the correct answer is 1 : 2.
Question : A sum of INR 10,500 amounts to INR 13,650 in 2 years at a certain rate percent per annum simple interest. The same sum will amount to what in 1 year at the same rate if the interest is compounded half yearly (nearest to INR 1 )?
Option 1: INR 12,124
Option 2: INR 12,134
Option 3: INR 12,143
Option 4: INR 12,314
Correct Answer: INR 12,134
Solution : Given, A sum of INR 10,500 amounts to INR 13,650 in 2 years at a certain rate percent per annum simple interest compounded half-yearly We know, Simple interest = $\frac{\text{Principal × rate × time}}{100}$ Amount = Principal(1 + $\frac{r}{100}$)t If interest is compounded
