Answer: 2.5
Step-by-step explanation:
Answer:
49% and 30% respectively
Step-by-step explanation:
Step one:
Given data
Principal = Rs. 4,200
Final Amount= Rs. 9282 respectively
time = 2 years and
time = 4 years
Required
The rate of interest for 2 and 4 years
Step two:
the compound interest formula is
A= P(1+r)^t
for 2 years
Substitute


the rate is 49%
For 4 years we have

![1+r= \sqrt[4]{\frac{9282}{4500} } \\\\1+r=\sqrt[4]{2.21} \\\\1+r= 1.30\\\\r=1.30-1\\\\r= 0.30\\\\](https://tex.z-dn.net/?f=1%2Br%3D%20%5Csqrt%5B4%5D%7B%5Cfrac%7B9282%7D%7B4500%7D%20%7D%20%5C%5C%5C%5C1%2Br%3D%5Csqrt%5B4%5D%7B2.21%7D%20%20%5C%5C%5C%5C1%2Br%3D%201.30%5C%5C%5C%5Cr%3D1.30-1%5C%5C%5C%5Cr%3D%200.30%5C%5C%5C%5C)
the rate is 30%
1. I would multiply the dimensions of each room to find the area of each room. Then I can add up the areas to get the total area.
2. (24.5x16)+(15x12.75)+(10.5x10.5)
3. 392+191.25+110.25 = 693.5 ft²
Say the total allowance is X.
4/9X=$28
Therefore 28/(4/9) = $63
