Correct Answer: Rs. 405

Solution : We know,
Equivalent single discount = $(a+b-\frac{a×b}{100}$)%,
Where $a,b$ are successive discounts.
So, $10+10-\frac{10\times 10}{100}=19$%
$\therefore$ Required selling price = (100 – 19)% of 500 = $\frac{500 \times 81}{100}$ = Rs. $405$
Hence, the correct answer is Rs. 405

Correct Answer: 0.025

Solution : Given: 1% of 1% of 25% of 1000
= $\frac{1}{100}×\frac{1}{100}×\frac{25}{100}×1000$
= $0.025$
Hence, the correct answer is 0.025.

Correct Answer: $10:9$

Solution : Given:
$\frac{A}{B} = \frac{3}{4}$ and $\frac{B}{C} = \frac{6}{5}$
Multiplying both the equations we get,
$\frac{A}{B}\times \frac{B}{C} = \frac{3}{4}\times\frac{6}{5}$
$\frac{A}{C} = \frac{9}{10}$
⇒ $\frac{C}{A} = \frac{10}{9}$
$\therefore C: A=10:9$
Hence, the correct answer is $10:9$

Correct Answer: INR 4,080

Solution : Given, Principal, P = INR 50,000
Rate of interest $r$ = 8% per annum compounded half-yearly
= 4% per half-year
Time = 1 years with half-yearly interest = 2 half years
Amount = P × $(1+\frac{r}{100})^{\text{Time}}$
= 50000$(1+\frac{8}{2\times 100})^{2}$
= 50000$(1+\frac{4}{100})^{2}$
= 50000$(\frac{26}{25})^{2}$
=
