- C. 34.652
- D. 26.354
- Correct Answer
- 36.975
Explanation30 + (.0825 x 30) + (15% x 30)

Hence, from (1) & (2)
30 + (.0825 x 30) + (15% x 30)
= 30 + 2.475 + 4.5
30 + (.0825 x 30) + (15% x 30) = 36.975.

Correct Answer: Rs. 20
Explanation:
Let the original price of rice be Rs. x
Let rice a man can buy for Rs. 500 at rs. x/kg be = R kgs
From given data, for Rs. 500
x ---- R kgs
(x + 25x/100) ---- (R - 5) kgs
=> Rx = (R - 5)(x + 25x/100)
=> Rx = (R - 5)(125x/100)
=> 100Rx = 125Rx - 625x
=> R = 25
So at rate of Rs. x/kg, man get 25 kgs for Rs. 500
=> x = 500/25 = Rs. 20
Correct Answer: 87%
Explanation:
=>x = 174 => 87%
Correct Answer: 8 + 15/17
Explanation:
Total sales tax paid = 7% of Rs, 400 + 9% of Rs. 6400
=Rs. (7/100)*400 + (9/100)*6400 = Rs. (28 + 576) = Rs. 604.
Total cost of the items = Rs. (400 + 6400) = Rs. 6800.
Required percentage =(604/6800*100) % = %.
Correct Answer: 44 %
Explanation:
n (A) = 34, n (B) = 42, n (A ? B) = 20.
So, n (A U B) = n (A) + n(B) - n(A ?B) = 34 + 42 - 20 = 56.
Percentage failed in either or both the subjects = 56.
Hence, percentage passed = (100 - 66)% = 44%.
Correct Answer: 50%
Explanation:
Number of runs made by running = 120 - (3 x 4 + 8 x 6) = 120 - (60) = 60

Explanation:
Let the salary of Karthik 2 years ago be Rs.100
So, Lucky's salary 2 years ago was Rs.50
Karthik's present salary has seen two 10 percent increases. So as Lucky's salary.
So, Karthik's salary 1 year ago = 100 + 10% of 100 = 100 + 10 = 110.
Karthik's present salary = 110 + 10% of 110 = 110 + 11 = 121.
Lucky's salary 1 year ago = 50 + 10% of 50 = 50 + 5 = 55
Lucky's present salary = 55 + 10% of 55 = 55 + 5.5 = 60.5
Lucky's present salary of 60.5 = 50% of Karthik's present salary of 121.
