They given 2 I ratings and V1 rating and asked to find the v2 value.
R = V/I.
V1/I1 = 24/120 = 8=R2.....For V1--------1.
V2/I2 = v2/160 = V2/4 = R2..For V2--------2.
Equate 2 Epns,
8 = V2/4
V2 = 32 volts.
R = V/I.
V1/I1 = 24/120 = 8=R2.....For V1--------1.
V2/I2 = v2/160 = V2/4 = R2..For V2--------2.
Equate 2 Epns,
8 = V2/4
V2 = 32 volts.

Here is two currents rating then we apply ohms for two voltage rating like V1/I1 = V2/I2 So,
24/120 =V2 /160,
8/1 = V2/4,
V2= 32 Volt.
24/120 =V2 /160,
8/1 = V2/4,
V2= 32 Volt.

V is directly proportional to I (i.e) go with @Ashutosh is very smart.

V1/I1 = V2/I2.
24/120 = V2/160.
V2 = 32Volt.
24/120 = V2/160.
V2 = 32Volt.

Hi santosh its obviously ohms law, since we are doing problems under ohms law subtitle.

Hi nikul which formula you are using to solve this, may I know the name of the formula.

With help of maths therasuit
120mA - 24V
Then 160mA - (?) (How Much)
Means 160*24/120 = 32V
120mA - 24V
Then 160mA - (?) (How Much)
Means 160*24/120 = 32V
