The Correct Option is B
Solution and Explanation
The series follows a similar pattern that is,
12 × 1 − 1 = 11
11 × 2 + 2= 24
24 × 3 - 3 = 69
69 × 4 + 4 = 280
280 × 5 - 5 = 1395
1395 × 6 + 6 = 8376
The Error Term is 72
The Term which will Replace it will be 69

Mr. Kunal Dwivedi wants to buy a motorbike which is priced at Rs. 45,000. The bike is also available at Rs. 25,000 down payment and monthly installments of Rs. 1000 per month for 2 years or Rs. 18,000 down payment and monthly instalment of Rs. 1000 per month for 3 years. Mr. Kunal has with him only Rs. 12,000. He wants to borrow the balance money of the down payment from a private money lender whose terms are :
If Rs. 6,000 is borrowed for 12 months, the rate of interest is 20%. The interest will be calculated on the whole amount for the whole year, even though the repayment has to be done in 12 equal monthly instalments starting from the first month itself. Thus he will have to repay an amount of Rs. 600 per month for 12 months to repay Rs. 6000 (Principal) + Rs. 1,200 (Interest @ 20%).
If Rs. 10,000 upwards is borrowed for one year, the rate of interest is 30% and is calculated in exactly the same manner as above. - Refer to the following charts given in Fig 1, 2 & 3 to answer these questions.
