SSC CGL 2025 Tier-I · 12 September 2025, Shift 1 · General Intelligence and Reasoning · Question 1 of 100

Text as printed on a candidate's response sheet for this shift; answer per SSC's tentative key as marked on that sheet. Solution last reviewed 11 September 2026.

Where this paper and its answers come from

SSC does not publish CGL question papers or a public answer key. From 2025 the candidate response sheet prints every question and option as a picture, so the text here is transcribed from those pictures for this shift and checked against them independently; where the layout carries meaning, the picture is shown as well. Each answer is the key SSC colour-marked on that sheet. SSC released a tentative key for challenge and later its final one, both only to candidates behind a login, and the sheet does not say which of the two it carries. The solutions are written by UnlockIAS.

In the following question, select the related word from the given alternatives. Watt : Power :: Pascal : ?

(a)Energy
(b)Temperature
(c)Pressure
(d)Force

Answer

Why

Correct — C.
Rule: unit : the quantity it measures.

The watt is the SI unit of power: 1 W is one joule per second.
The pascal is the SI unit of pressure: 1 Pa is one newton per square metre.

Pascal : Pressure repeats Watt : Power → option (c).

Why the others are wrong

(a)
Energy — Energy is measured in joules, not pascals. It tempts because it hides inside the first pair — a watt is one joule per second — but it is not what a pascal measures.
(b)
Temperature — Temperature is measured in kelvin. A pascal measures a force spread over an area, which says nothing about how hot a body is.
(d)
Force — Force is measured in newtons. The pascal is built from the newton, one newton per square metre, but dividing by area turns force into pressure.

Concept

A unit analogy pairs an SI unit with the physical quantity it measures. Read the first pair to fix the direction — here it is unit first, quantity second — then name what the second unit measures.

The trap is a unit's ingredients. The pascal is defined as a newton per square metre, so force sits inside it. The quantity it names is still pressure.

Every option is a physical quantity, so recognising the pascal as a unit is not enough. Force is the nearest miss, because the newton appears inside the pascal's definition.

Key facts

The watt is the SI unit of power: 1 W = 1 joule per second.
The pascal is the SI unit of pressure: 1 Pa = 1 newton per square metre.
Energy is measured in joules, force in newtons and temperature in kelvin.

SI units of electrical quantities: ampere, volt, ohm, coulombDerived SI units and the base units they are built fromUnit analogies written quantity first, such as Frequency : Hertz

Common traps

Choosing force because the newton appears in the pascal's definition
Choosing energy because it links to the watt in the first pair

Here SSC writes the unit first and the quantity second.
