- D. 511
- E. 556
The series is 7, 26, 124, ___, 342, ___
The terms are (2^3-1), (3^3-1), (4^3-1), (5^3-1), (6^3-1), (7^3-1),...
The missing numbers are 6^3-1= 215 and 8^3-1= 511

2. Question:
Sugar at Rs. 15 per kg is mixed with sugar at Rs. 20 per kg in the ratio 2:3. Which of the following is true? Indicate all correct options.
- A. The price per kg of the resulting mixture is Rs. 17 per kg
- B. The price of the resulting mixture is Rs. 18 per kg
- C. The price of the resulting mixture is Rs. 17.50 per kg
- D. The selling price per kg of selling the sugar at 5% profit is Rs. 20
- E. The selling price per kg of selling the sugar at 10% profit is Rs. 19.80
Let the quantity of sugar at Rs.15 and at Rs.20 per kg be 2x and 3x kg respectively
Total quantity = 2x+3x=5x
Price per kg of resulting sugar = (2x*15+3x*20)/5x
= (30x+60x)/5x
= 90x/5x = Rs.18
Option B is true and A and C are false.
Cost price (CP) of sugar = Rs. 18
Let selling price be SP
SP = (100+gain%)CP/100
= (100+5)18/100
= 105*18/100
= Rs.18.90
Option D is false.
