4.2

distance/speed

330/110= 3

So it'll take 3 hours

4.3

sorry not sure for this one :(

4.1

Cost of 22ltrs of petrol = Rs300

Cost of 1ltr of petrol = 300/22

= 150/11

= Rs13.63

4.2

distance = 330km = d

speed = 110km/hr = s

time = d/s

= 330/110

= 33/11

= 3hrs

4.3

SI = principal amount × rate of interest × time

[tex] = 2000 \times \frac{9}{100} \times 4[/tex]

[tex] = 20 \times 9 \times 4[/tex]

[tex] = 720[/tex]

Amount = Principal + SI

= 2000 + 720

= Rs2720

Hamid has gained weight.
He now weighs 88kg, whish is higher than his normal weight
What is Hamid's normal weight?

Answers

The situation we have to find is how much weight Hamid has gained. There is no number so I’m just going to teach u how to find the original weight. So basically you have to subtract the weight that is gained from the current weight which will give you the answer to the normal weight.
Current weight-weight gained=normal weight
For example if he gained 5 kg
88-5=83 so his normal weight is 83kg
