Mr Satyal borrowed Rs 50000 and after ane year she returned the loan by paying 60000. What is the intrest paid and what is the r
Hatshy [7]

The interest paid is Rs 10000

The rate of interest  is  20%

Step-by-step explanation:

Step 1 :

Amount  borrowed by Mr. Satyal = Rs 50000

Amount repaid  = Rs 60000

Interest is charged on the principal amount and the amount repaid will be the sum of the interest paid plus the principal amount

Hence the interest paid is 60000 - 50000 = Rs 10000

Step 2:

The rate of interest is  calculated as follows :

Divide the interest calculated by the principal amount and is expressed as percentage.

Hence the interest rate  = \frac{10000}{50000} × 100 = 20%

Step 3 :

The interest paid is Rs 10000

The interest rate  is  20%

PLEASE HELP IT WOULD BE VERY MUCH APPRECIATED! Last year, James earned £1,600 per month.
True [87]
Answer: £11.69

Explanation:

1) Work out 2% of £1600:
1600 x 2/100 =36

2) Add it on to the original number to get his new monthly pay:
1600 + 36 = £1636

3) Work out his yearly pay by:

a) finding the amount of months he worked:
46 / 4 = 11.5 months

b) Divide 11.5 into 2 bits and add them on:
1636 x 11 = 17997
1636 x 0.5 = 818

17997 + 818 = £18814

4) To get his pay per week:

18814 / 46 = £409

5) Finally, to get his pay per hour:

409 / 35 = 11.68671...
= £ 11.69
