Trade Deficit of a Country (in Crores of Rupees)
The deficit in 1993-94 was roughly how many times the deficit in 1990-91?
Option 1: 1.4
Option 2: 1.5
Option 3: 2.5
Option 4: 0.5
Correct Answer: 1.5
Solution : Deficit in 1993-94 = 4200 Deficit in 1990-91 = 2800 Required value = $\frac{4200}{2800}$ = $\frac{3}{2}$ = $1.5$ Hence, the correct answer is 1.5.
Question : A man is born in the year 1896 A.D. If in the year $x^2$ A.D. His age is $(x-4)$, the value of $x$ is:
Option 1: 40
Option 2: 44
Option 3: 36
Option 4: 42
Correct Answer: 44
Solution : Let the man's age be $x$. According to the question, $x^2 - 1896 = x - 4$ or, $x^2 - 1896 - x + 4 = 0$ or, $x^2 - x - 1892 = 0$ or, $x^2 - 44x + 43x - 1892 = 0$
Question : $\triangle \mathrm{ABC}$ is an isosceles triangle with $\angle \mathrm{ABC}=90^{\circ}$ and $\mathrm{AB}=\mathrm{BC}$. If $\mathrm{AC}=12 \mathrm{~cm}$, then the length of $\mathrm{BC}$ (in $\mathrm{cm}$) is equal to:
Option 1: $6 \sqrt{2}$
Option 2: $8$
Option 3: $6$
Option 4: $8 \sqrt{2}$
Correct Answer: $6 \sqrt{2}$
Solution : Given, $\triangle \mathrm{ABC}$ is an isosceles triangle with $\angle \mathrm{ABC}=90^{\circ}$, $\mathrm{AB}=\mathrm{BC}$, and $\mathrm{AC}=12 \mathrm{~cm}$ According to Pythagoras theorem, $AC^2=AB^2+BC^2$ ⇒ $12^2=2\times BC^2$ ⇒ $BC^2= 72$ ⇒ $BC=6\sqrt2$ cm Hence, the correct answer is $6\sqrt2$.
