What will be the compound interest on a sum of Rs. 22,000 after 3 years at the rate of 12% p.a.? | [
"s.8908.41",
"s.10123.29",
"s.6123.20",

The no. of gift pack bought by Dexter is 1 more than the price, in rupees, of each gift pack. The amount of Rs.380 which Dexter had, fell short of the required amount. What is theamount by which he might have fallen short. | [
"Rs 30",

Then number of packs bought =a+1=a+1
Hence total cost is a(a+1)a(a+1)
It is given that 380<a(a+1)380<a(a+1)
If a=19a=19, the total cost =19×20=380=19×20=380
Dexter would not have fallen short, If:
a=20a=20, a(a+1)=420a(a+1)=420

"10 months",
"7 months",
"None of these",
"8 months"
] | D | Let B join after x months of the start of the business so that B’s money is invested for (12 – x) months.
∴ Profit ratio is 12 × 12500 : (12 – x) × 37500
or 12 : 3(12 – x)
Since profit is equally divided so
12 = 3(12 – x) or x = 8. Thus B joined after 8 months.
