Page 96 of "The Jet Engine" - published by Rolls Royce:
"The control of power or thrust of the gas turbine engine is effected by regulating the quantity of fuel injected into the combustion system. When a higher thrust is required,the throttle is opened and the pressure to the fuel spray nozzles increases due to the greater fuel flow. This has the effect of increasing the gas temperature, which in turn increases the acceleration of the gases through the turbine to give a higher engine speed and a correspondingly greater airflow, consequently producing an increase in engine thrust."

JD2016 has left comment on pB1B2's question:
Or alternatively,another equivalent way which doesn't involve algebra is to say:
If you got 15% discount, then what you actually paid was 85%. So 4500 is 85% or 85/100 (eighty five hundredths). The price before discount is 100/100. So divide 4500 by 85 and multiply it by 100 to get the price before discount. You could also say that 15% is 3/20 (three twentieths) so that 4500 is 17/20 - so divide by 17 and multiply by 20 - but its the same thing. Read comment

dimky has left comment on pB1B2's question:
Hi!

x - (x * 15 / 100) = 4500
x - 0.15x = 4500
0.85x = 4500
x = 4500 / 0.85
x = 5294 (5300 as answer)

This question requires you to know how to make and solve equations. Read comment

Hi.
Area of a ring is pi * (R^2 - r^2)
Area in this question is = pi * (25 - 9) = pi * 16 cm^2 Read comment
