Correct Answer: Rs. 2525
Explanation:
Let his income be Rs. N, then N - 5% of N - 20% of 95% of N = 1919
? N - N/20 - (20 x 95 x N)/(100 x 100) = 1919
? N - N/20 - 19N/100 = 1919
? 100N - 5N - 9N = 191900
? N = 191900 / 76 = 2525
Correct Answer: 4000
Explanation:
Let salary be Rs. A, then A - 15 % of A - 30% of 85% of A = 2380
? A - 15A/100 - (30 x 85 x A)/(100 x 100) = 2380
? 200A - 30A - 51A = 2380 x 200
? 119A = 2380 x 200
? A = (2380 x 200)/199 = 4000
Correct Answer: 16.66%
Explanation:
CP of the chair which is sold at 25% of profit = Rs 4000/ (1+ 25%)
= Rs 4000/1.25
= Rs 3200
Now given, that sum of CP pf table and chair= sum of SP of table and Chair
? 8000= 3200 + CP of Table
? CP of Table = Rs 4800
? Loss on Cost price of table = Rs 4800- Rs 4000= Rs 8000
? Loss % = 8000/4800 = 16.66%
Correct Answer: 21
Explanation:
10% of 100 = 10
New price = 110
Again, 10% of 110 = 110 x (10/100) = 11
New price = 110 + 11 = 121
? Required increment = 121 - 100 = 21
Correct Answer: 25%
Explanation:
Given, a = 20%
Required percentage = [a/(100 - a)] x 100%
= [20/(100 - 20)] x 100%
= (20/80) x 100%
= 25%
Correct Answer: 120
Explanation:
? 721/2% of N = 87
? {(145/2) x N} / 100 = 87
? N = (87 x 2 x 100) / 145 = 120
Correct Answer: 10%
Explanation:
Let third number be N
Then, first number = 70% of N = 7N/10 and,
Second number = 63% of N = 63N/100
Difference = 7N/10 - 63N/100 = 7N/100
? Required percentage = (7N/100) x (10/7N) x 100 % = 10%
Correct Answer: 600
Explanation:
? (62% of N - 38% of N) =144
? 24% of N = 144
? N = (144 x 100)/24 = 600
Correct Answer: 1 : 6
Explanation:
Reduction in consumption = (20/120) x 100% = 50/3%
? Reduction in consumption /Original consumption = (50/3) / 100 = 1/6 = 1 : 6
Correct Answer: 4% decreased
Explanation:
Let tax = Rs. 100 and Consumption = 100 units
Original expenditure = Rs. (100 x 100) = 10000
New expenditure = Rs. (120 x 80) = Rs. 9600
? Decreased in expenditure = (400 x 100)/1000 % = 4%
