Answer is:
1600
Explanation:
Formula : N1/N2 =V1/V2 (Turns Ratio)
Where N is the number of turns in the coil and V is the voltage across the coil. Subscript 1 denotes primary side and subscript 2 denotes secondary side.
Therefore N2=N1*(V2/V1)
N2=1000*(400/250)
N2= 1600 turns.
1600 turns are required in the secondary coil to induce a voltage of 400V in the secondary side when the primary side voltage is 250V.
This is known as a step up transformer.

Answer is:
20 years
Explanation:
12 years ago his age was x−12
12 years later his age will be x+12
As per problem the following equation can be formed
x+12=4(x−12)
⇒x+12=4x−48
⇒x−4x=−12−48
⇒−3x=−60
⇒x=20
His present age is 20 years.
