Answer:

Motors 175 kVA

Lighting 315 kVA

Other loads 35 kVA

Explanation:

The total load on a certain service is 525 kVA.

One-third of this load is from motors, then

$(1)/(3)\cdot 525=175\ kVA$

is from motors.

(3)/(5) is lighting, then

$(3)/(5)\cdot 525=3\cdot 105=315\ kVA$

is lighting.

(1)/(15) is from other loads, then

$(1)/(15)\cdot 525=35\ kVA$

is from other loads.
