Each letter is shifted by +1. C->D, H->I, A->B, I->J, R->S. So, CHAIR = DIBJS.

Each letter is shifted by +1. C -> D, H -> I, A -> B, I -> J, R -> S. So, CHAIR = DIBJS.

Each letter is shifted by +1. F->G, I->J, R->S, E->F. So, FIRE = GJTF.

If 2 pencils cost 50 cents, then 10 pencils (5 times more) will cost 5 * 50 = 250 cents or $2.50.

'C' = 3, 'A' = 1, 'T' = 20. So, 3 + 1 + 20 = 24.

CAB = 3, 1, 2 = 321

Folding a circular paper in half results in a semi-circle when unfolded.

At 3:15, the hour hand is at 97.5 degrees (3*30 + 15*0.5) and the minute hand is at 90 degrees (15*6). The angle between them is 97.5 - 90 = 7.5 degrees.

If A is greater than B and B is greater than C, then A must be greater than C.

B is married to A and they have a child C, making B the mother of C.

The arrangement is D, A, B, C. B is in the middle.

The arrangement is B, A, C, D. A is in the middle.

A is the brother of B, and C is the sister of B, so A is also the brother of C.

A is the husband of C as they are the parents of B.

A is the sister of B, and since B is the father of C, A is C's aunt.

C is the sister of A as both are children of B.

Since A is to the left of B and B is to the right of C, it follows that A is to the right of C.

A is to the left of B, and C is to the right of B, so A is to the left of C.

The triangle will be visible when the paper is unfolded.

The paper will return to its original square shape when unfolded.

Option 3 completes the pattern correctly after a 90-degree clockwise rotation.

Turning 180 degrees from East leads to West, and turning left from West leads to South.

Starting from East, turning 270 degrees clockwise means he turns to South, then to West, and finally to North.

Turning 270 degrees clockwise from east will face him west.

Turning left from East leads to North. Turning 180 degrees from North leads to South.

Turning 45 degrees right from North leads to East. Turning 135 degrees left from East leads back to North.

Starting from North, a 90 degrees clockwise turn leads to East. A 180 degrees anti-clockwise turn from East leads to West.

Starting from North, turning 90 degrees right leads to East. Turning 180 degrees left from East leads to South.

Starting from North, walking 5 steps keeps him facing North. Turning left leads to West, and walking 3 steps keeps him facing West.

Turning 180 degrees from South will make him face North.
