Correct Answer: INR 2,500

Solution : Given: Compound interest = 981
$r=18$%
$t=2$ years
Solve by using the formula: Compound interest = $P[(1+\frac{r}{100})^{t}–1]$ to get the desired value where $P$ is principal, $r$ is the rate of interest and $t$ is the time in years.
Putting the value in the

Correct Answer: $\frac{5}{4}$

Solution :
$\triangle \mathrm{RMS}$ is a right-angled triangle
⇒ $SR^2=SM^2+MR^2$
⇒ $SR^2=3^2+4^2=9+16=25$
⇒ $SR=\sqrt{25}=5$
$\therefore$ $\sec R =\frac{SR}{MR}=\frac{5}{4}$
Hence, the correct answer is $\frac{5}{4}$.

Correct Answer: 20

Solution : Given:
19 ÷ 2 – 35 + 10 × 6 = ?

After replacing the signs as per the direction given in the question, the equation becomes –
19 + 2 × 35 ÷ 10 – 6
= 19 + 2 × 3.5 – 6

Correct Answer: $0$

Solution : $\tan (50°+\theta)-\cot(40°-\theta)$
We know, $\cot(90°-x)=\tan x$
$=\tan(50°+\theta)-\cot(90°-(50°+\theta))$
$=\tan(50°+\theta)-\tan(50°+\theta)$
$=0$
Hence, the correct answer is $0$.

Correct Answer: $\frac{1}{16}$

Solution : Given: $\sqrt{y}=4x$
Squaring on both sides,
⇒ $y = (4x)^2 = 16x^2$
⇒ $\frac{x^2}{y}$ = $\frac{1}{16}$
Hence, the correct answer is $\frac{1}{16}$.
