Answer:
Step-by-step explanation:
The simple interest on a certain sum for 5years at 8% per annum is Rs200 less than the simple interest on the same sum for 3years and 4months at 18% per annum.Find the sum
The formula for Simple Interest = PRT
From above question, we have to find the Principal
The simple interest on a certain sum for 5years at 8% per annum is Rs200
Hence,
R = 8%
T = 5 years
Rs 200 = P × 8% × 5
P = 200/8% × 5
P = Rs500
The principal = Rs 500
The simple interest on the same sum for 3years and 4months at 18% per annum.
Simple Interest = PRT
R = 18%
T = 3 years and 4 months
Converted to years
T = 3 + (4 months/12 months)
T = 3.33 years
Hence,
Simple Interest = Rs 500 × 18% × 3.33 years
= Rs 299.7
Answer:
he can do a lap in 14 seconds
and he can swim 4 laps in 56 seconds
Step-by-step explanation:
21/20 ,because 0.5 is 1/20 of the whole number 1,so 20/20 + 1/20=21/20
Answer:
P(hit)=0.4
Step-by-step explanation:
In his practice, his probability of getting a hit was 6/15 or 0.4. This counts as an experiment, so the probability of him getting a hit again is the same, 0.4.
