Question
Rohit used to earn Rs. 42,000 per month. His spending to
saving ratio was 5:9. After a salary increment, he reduced his expenses by 20% and his savings increased by 20%. What was the hike in his salary?Solution
ATQ,
Initially, expenditure of Rohit = 42000 × (5/14) = Rs. 15,000
Initially, savings of Rohit = 42000 × (9/14) = Rs. 27,000
After salary hike, expenditure = 15000 × (80/100) = Rs. 12,000
After salary hike, savings = 27000 × (120/100) = Rs. 32,400
So, increased salary = 12000 + 32400 = Rs. 44,400
Required salary hike = 44400 – 42000 = Rs. 2,400
(20% of 15% of 600 – 6) × 5 + 84 = ?2Â
180 ÷ 3 of 2 = 102 – ?
The sum of two numbers is 16 and their product is 63. The sum of their reciprocal is equal to:
∛21952 × 44 = ? × 14
What will come in the place of question mark (?) in the given expression?
(√1089 + 84 ÷ 2) % of 348 = 416 - ?
What will come in the place of question mark (?) in the given expression?
{(16 × 25) ÷ 32} × 12 = ? – 200
- What will come in place of (?) in the given expression.
(18 × 2) + (72 ÷ 3) – 16 = ? 13 X √? + 256 ÷ 4 = 30% of 900 - 50
1365 ÷ 15 + (? ÷ 5) = 62 × 3.5
