- A principal was put at a certain rate of interest for four years. Had it been put at a rate of interest 4% higher than the previous rate interest, it would have fetched Rs. 80 more. What is the principal?
Rs 450Rs 500Rs 400Rs 550None of theseOption B

y*4*(r+4)/100 – (y*4*r)/100 =80

4yr+16y – 4yr = 8000

y= 8000/16 =Rs 500 - A bottle is priced at 15000 Rs. But a person wants instalment on the bottle. So he gaves 10000 rupee cash and make an installment of Rs 650 for 8 months. Find the rate of interest charged by the shopperson?
4%6%3%8%None of theseOption B

Total amount buyer gives = 10000 + 650*8 = 15200

=, 200 = 5000*(8/12)*R/100 - Shivani invested 20000 rupee in FD at the rate of 10% simple interest. After every 3rd year she added interest to principal. Find the interest earned at end of 6th year?
Rs 7500Rs 7400Rs 7800Rs 7600None of theseOption C

For the first 3 years Simple Intrest will be = 20000*10/100*3 = Rs 6000

Now she add Rs 3000 to the principal= 20000+6000 = Rs 26000

Now interest earned at end of 6th year = 26000*10/100*3 =Rs 7800 - The SI on a certain sum is 4/9 th of principal and numbers of year is equal to the rate of interest. The rate of interest will be which of the following?
20/3 %16/3%13/3%17/3%None of theseOption A

4/9* P = P *R /100 * R - Akansha divides Rs 4702 among X, Y, and Z, so that if the amounts being invested at 4% SI, the amounts received after 2, 3 and 4 yrs by X, Y, and Z respectively is equal. Find the share of Y?
Rs 1556Rs 1450Rs 1655Rs 1750None of theseOption A

=1/[100+rt1] : 1/[100+rt2] : 1/[100+rt3]=1/[100+4*2] : 1/[100+4*3] : 1/[100+4*4]=1/108 : 1/112 : 1/116

= 812 : 783 : 756

So Y gets 783/(812+783+756) * 4702 = Rs 1566 - What annual payment will give a debt of Rs 15,750 due 3 years with ROI being 5% p.a.?
Rs 6500Rs 6000Rs 5000Rs 4500Rs 5500Option C

Intrest = 100*A / [100*t + rt(t-1)/2] - Akansha borrowed Rs 2500 and some money from Banya and Caryl respectively at 7% rate. After 4 years Akansha pays a total of Rs 1120 as simple interest to Banya and Caryl. What is the sum borrowed from Caryl?
Rs 1500Rs 1200Rs 1875Rs 1955None of theseOption A

2500*7*4/100 + y*7*4/100 = 1120 - If the difference between SI and CI on some principal amount at 20% for 3 years is Rs. 48, then the principal amount is which of the following?
Rs 350Rs 375Rs 415Rs 445None of theseOption B
- What principal invested for 2 years at 12% compounded annually will grow toRs.4390.4?
Rs 3200Rs 3500Rs 3550Rs 3750Rs 3150Option B
- Divide Rs. 3903 between Akansha and Banya, so that Akansha’s share at end of 7 years may equal to Banya’s share at end of 9 years, compound interest being at 4 percent?
Rs 2145 and Rs 1825Rs 2028 and Rs 1875Rs 2020 and Rs 1750Rs 3050 and Rs 1950None of theseOption B

Dividing Rs. 3903 in the ratio of 676:625

Akansha’s present share = 676 of Rs. 3903

=(676+625)

= Rs. 2028

Banya’s present share = Rs. 3903 – Rs. 2028

=Rs. 1875
