—
🔹 Step 1: Approximate each number
* $\frac{0.89}{31.88} \approx \frac{0.9}{32} \approx 0.028$
* So expression becomes:
$67.96 + 5.12 - 0.028 \approx 67.96 + 5.12 = 73.08,\ \text{then}\ 73.08 - 0.028 \approx 73.05$

B) ₹12,275
C) ₹12,175
D) ₹12,225

View Answer

D) ₹12,225

Explanation:We are given:
* Time = 7 years
* Amount at x% = ₹22,494
* Amount at (x + 4)% = ₹25,917
* Need to find the principal (sum invested)
—
Shortcut Method (based on Simple Interest formula):
$\text{Simple Interest (SI)} = \frac{P \cdot R \cdot T}{100}$
Let $P$ be the principal.
Let’s find the difference in amounts due to rate increase:
₹25,917 – ₹22,494 = ₹3,423
This ₹3,423 is the extra interest earned over 7 years due to the extra 4% rate.
So we write:
$\frac{P \cdot 4 \cdot 7}{100} = 3423 \Rightarrow \frac{28P}{100} = 3423 \Rightarrow P = \frac{3423 \cdot 100}{28} = 12,225$
