Question
Priya’s salary was Rs. 36,000 with an expenditure to
savings ratio of 2:7. After a hike, her expenditure dropped by 10% and her savings went up by 30%. What was her new salary hike?Solution
ATQ,
Initially, expenditure of Priya = 36000 × (2/9) = Rs. 8,000
Initially, savings of Priya = 36000 × (7/9) = Rs. 28,000
After salary hike, expenditure = 8000 × (90/100) = Rs. 7,200
After salary hike, savings = 28000 × (130/100) = Rs. 36,400
So, increased salary = 7200 + 36400 = Rs. 43,600
Required salary hike = 43600 – 36000 = Rs. 7,600
What will come in place of the question mark (?) in the following questions?
?= √(4 × ∛(16 × √(4 × ∛(16 ×…… ∝)) ) )
560 ÷ 14 × 3 – 25 = ?
What value will come in place of (?) question mark in the given expression.
√144 × √81 + 7² – 5³ = ?
56 x 8 – 65% of 40 = ? + 14 x √625
3(2/3) of 2(5/11) of 5(2/5) of 75 = ?
18 × 15 + 86 – 58 =? + 38
What value should come in the place of (?) in the following questions?
222 + 322 – 508 = ? * 5
25.6% of 250 + √? = 119
