Represent the following statement with suitable integers. i) Sneha deposited 2000 in her saving account.
Answers
Step-by-step explanation:
Principal amount deposited (P) = Rs 2000
Time period (T) = 1 year
Rate of interest (R) = 6% p.a.
Interest after 1 year =
100
P×R×T
=
100
2000×6×1
= Rs 120
So, amount after 1 year = Principal amount + Interest = 2000 + 120 = Rs 2120
After 1 year , amount withdrawn = Rs 700
Principal amount left (P1) = Rs 2120 - Rs 700 = Rs 1420
Time period (T) = 2 years
Rate of interest (R) = 6% p.a.
Interest after 2 years =
100
P×R×T
=
100
1420×6×2
= Rs 170.40
Total amount after 3 years = Rs 1420 + Rs 170.40 = Rs 1590.40
Answer:
The above statement can be represented as: (+) 2000 Rupees.
Step-by-step explanation:
We use the concept of positive and negative integers to represent the given statements as integers with appropriate signs.
Whenever there is an increase/above/addition/deposit, we use a positive sign (+) whereas, whenever there is a decrease/reduction/below/withdrawal, we use the negative sign (-).
Let any amount of money deposited be positive while any amount of money withdrawn be negative.
Then the above statement can be represented as: (+) 2000 Rupees.
