24 × 3 + 1 = 73

73 × 3 + 2 = 221

221 × 3 + 3 = 666

666 × 3 + 4 = 2002

7 × 1.5 + 0.5 = 11

11 × 2 + 1 = 23

23 × 2.5 + 2 = 59.5

59.5 × 3 + 4 = 182.5

–2—4—6—8— - The sum of eight consecutive even numbers of set-A is 376. What is the sum of different set of five consecutive numbers whose lowest number is 15 more than the mean of set-A ?
220320330400120Option B

Mean of set A = 376/8 = 47

The lowest number of second set = 47 + 15 = 62

Required = 62 + 63 + 64 + 65 + 66 = 320 - Sunetra invested an amount of Rs. 50,000 to start a software business. After six months Nikhil joined her with an amount of Rs 80,000. At the end of 3 years they earned a profit of Rs. 24,500. What is Sunetra’s share in in the profit ?
Rs. 17,550Rs. 20,000Rs. 15,500Rs. 12,000Rs. 10,500Option E

The ratio of capital invested by each partner i.e. Sunetra and Nikhil for in order to get the same profit is : 36 × 50000 : 30 × 80000 = 3 : 4

Share of Sunetra out of Rs. 24500 = Rs.3/7 × 24500 = Rs. 10,500 - The Simple interest accrued on an amount of Rs.18000 in 2 years is less than the compound interest for the same period by Rs.180. What is the rate of interest?
