Q 1 - An aggregate of cash at basic premium adds up to Rs 2240 in 2 years and Rs 2600 in 5 years. The total:
Answer : B
Explanation
S.I for 3 year = (2600-2240) = Rs.360 S.I for 1 year = 360/3 = 120 Rs. S.I for 2 year =120*2=240 Rs. Sum = Rs. (2240-240) = 2000 Rs.
Q 2 - On the off chance that the basic simple interest on a certain total of cash for 15 months at 15/2 % p.a. surpasses the basic simple interest on the same aggregate for 8 months at 25/2 p.a. by Rs 32.50. The entirety is:
Answer : C
Explanation
Let the sum be rs. x. Then, (x* 15/2 *1/100*15/12)- (x*25/2*1/100*8/12) = 65/2 => 3x/32 ?x/12 = 65/2 => 9x-8x=3120 =>x= 3120 ∴ Sum = 3120
Q 3 - Simple interest on a sure whole at a sure yearly rate of interest is 25/16 of the entirety. In the event that the number speaking to rate percent and time in years is equivalent, then rate percent per annum is:
Answer : D
Explanation
Let the sum be Rs. x, Rate = R% P.a., time = 25/2 years. S.I = Rs. 25x/16 R = 100*25x/16 *1/x* 1/R => R2=2500/16 = R= 25/2 Hence, Rate = 25/2%
Q 4 - A commission operators permits a refund of 2% to a financial specialist while the organization pays on interest of 15% on the speculation. What rate of premium does the financial specialist really acquire on his venture?

Answer : B
Explanation
Let the sum be Rs. x. Then, S.I = Rs.2x/5 Rate = (100*S.I)/ (p*t) = (100*2x/5* 1/x*1/5) % p.a = 8% p.a.
Q 6 - Vishwas borrowed a total amount of Rs 30,000 part of it at 12 % per annum and remaining at 10% per annum. If at the end of two years he paid in all Rs 36,480 to settle the loan amount, what was the amount borrowed at 12 % per annum?
Answer : D
Explanation
Let the sum borrowed at 12% per annum be Rs x. So, sum borrowed at 10% per annum = Rs (30000 - x) Simple Interest = Rs 36480 ? Rs 30000 = Rs 6480 According to the question, x*2*12/100 + (30000 - x)*2*10/100 = 6480 or, 24x + 600000 - 20x = 648000 or, 4x = 48000 or, x = 12000
Q 7 - Simple interest on a certain amounts is 9⁄16 of the principal. If the numbers representing the rate of interest in percent and time in years be equal, then time, for which the principal is lent out, is?
Answer : C
Explanation
Let sum be z. Then,S.I = 9z⁄16 Let rate = R% and Time = R years therefore z x R x R⁄100 R2 900⁄16 R = 30⁄4 = 71⁄2 years.
Q 8 - An amount of Rs. 1,00,000 is invested in two types of shares. The first yields an interest of 9% p.a. and the second, 11% p.a. If the total interest at the end of one year is 93⁄4, then the amount invested in each share was?
Answer : A
Explanation
Let the sum invested at 9% be Rs. z and that invested at 11% be Rs. ( 100000 - z ). Then, z x 9 x 1⁄100 + (100000 - z) x 11 x 1⁄100 = 100000 x 39⁄4 x 1⁄100 = 9z + 1100000 - 11z⁄100
39000⁄4 = 9750 2z = (1100000 - 975000) = 125000 x = 62500 sum invested at 9% = Rs. 62500 sum invested at 11% = Rs. (100000 - 62500) = 37500
Q 9 - A sure entirety of cash adds up to rs. 756 in 2 years and to Rs. 873 in 7/2 years. Discover the aggregate and the rate of hobby.
Answer : A
Explanation
Sum in 7/2 years = Rs. 873, sum in 2 years= Rs. 756 S.I for 3/2 year = Rs. (873-756) = Rs. 117 S.I for a long time = Rs. (117*2/3*2) = rs. 156. Standard = (sum in 2 year) - (s.I for 2 year) = Rs. (756-156)= Rs. 600 Presently P = 600 Rs. T= 2 years. What's more, S.I = 156 Rs. ∴ R = (100*S.I)/P*T = (100*156)/ (600*2) = 13% P.a. Henceforth, aggregate = Rs. 600 and Rate = 13% P.a.
