Answer 1

Answer:

1. 4

2. 7.5 years

3. 13km

4. LOW

Step-by-step explanation:

1. 3x - y = 27 = 33     ⇔     x - y = 3 ....(i)

3x + y = 243 = 35     ⇔     x + y = 5 ....(ii)

On solving (i) and (ii), we get x = 4

2. Let the sum=x.

Then,S.I.=916x

Let rate=R%

And time=R years

∴(x×R×R100)=9x16⇒R2=90016R=304=712

Hence,time=7.5 years
