Correct Answer: INR 22,140


Solution : Given: Raju spends 10% and 20% of his income on transport and food respectively. He spends 30% of the remaining income on clothing.
Let Raju's income be INR $x$.
The transportation costs = 10% of $x$ = $0.10x$
The food costs = 20% of $x$ = $0.20x$
The income left over = $x - (0.10x + 0.20x)$ = $x - 0.30x$ = $0.70x$
The clothing expenses = 30% of $0.70x$ = $0.30 \times 0.70x$ = $0.21x$
The income left over = $0.70x - 0.21x$ = $0.49x$
His savings account for $0.49x$ times his salary.
⇒ $0.49x=26460$
⇒ $x=$ INR 54,000
The entire cost of clothes and food = $0.20x + 0.21x$.
⇒ $0.20\times 54000+0.21\times 54000=10800+11340 =$ INR 22,140
Hence, the correct answer is INR 22,140.
