Question
Sneha spent 12% and 18% of her monthly salary on
shopping and internet bills respectively. Out of the remaining amount, she spent 10% and 30% on gym and travel, respectively. Now she saved 25% of the remaining amount and the rest Rs. 31,500 was spent on household items. Find the amount spent by Sneha on travel.Solution
Let the monthly salary of Sneha = Rs. 100x Amount spent by Sneha on shopping and internet together = 12x + 18x = Rs. 30x Amount spent by Sneha on gym and travel together = 0.40 × (100x – 30x) = Rs. 28x Amount saved = 0.25 × (100x – 30x – 28x) = Rs. 10.5x So amount spent on household items = 0.75 × (100x – 30x – 28x) = 31500 31.5x = 31500 x = 1000 So the amount spent by Sneha on travel = 0.30 × 70 × 1000 = Rs. 21,000
