Ravi walks 3 km North, then turns right and walks 4 km. How far is Ravi from the starting point?
Correct answer: D. 5 km
The two legs are at right angles, so the distance is √(3² + 4²) = √25 = 5 km.
Solved reasoning MCQs on direction sense, ranking and order, calendars (days of the week) and clock angles, with worked solutions for SSC and banking exams.
A mixed reasoning set covering direction and distance, ranking in a row or queue, finding the day of the week for a date, and angles between the hands of a clock.
For directions, sketch the path on paper. For ranking, total = position from the left + position from the right − 1. For clocks, the angle is |30H − 5.5M|.
Correct answer: D. 5 km
The two legs are at right angles, so the distance is √(3² + 4²) = √25 = 5 km.
Correct answer: B. 10 km
The two legs are at right angles, so the distance is √(6² + 8²) = √100 = 10 km.
Correct answer: C. 13 km
The two legs are at right angles, so the distance is √(5² + 12²) = √169 = 13 km.
Correct answer: B. East
Plot the route: the steps cancel out along one axis and leave Kiran 5 km to the East of the start.
Correct answer: A. South
Plot the route: the steps cancel out along one axis and leave Sohan 3 km to the South of the start.
Correct answer: D. South
East → right → South → right → West → left → South. He faces South.
Correct answer: D. 18
Total = position from top + position from bottom − 1 = 7 + 12 − 1 = 18.
Correct answer: A. 20th
Position from right = total − position from left + 1 = 30 − 11 + 1 = 20.
Correct answer: B. 24
Total = 9 + 16 − 1 = 24.
Correct answer: A. 4
Students outside the gap: 14 (up to A) + 22 (up to B from the right) = 36. Between them: 40 − 36 = 4.
Correct answer: C. 32
After the swap Mona stands in Tina's old place, which is 18th from the left and 15th from the right. Total = 18 + 15 − 1 = 32.
Read detailsCorrect answer: C. Friday
Using the calendar, 15 August 1947 was a Friday.
Correct answer: D. Thursday
Using the calendar, 26 January 1950 was a Thursday.
Correct answer: D. Monday
The year in between has 365 days (52 weeks + 1 day) because 2027 is not a leap year, so the day moves forward by one: Sunday → Monday.
Read detailsCorrect answer: C. 365
A century year is a leap year only if it is divisible by 400. 1900 ÷ 400 is not a whole number, so 1900 was not a leap year (2000 was), so it had 365 days.
Read detailsCorrect answer: D. 90°
Angle = |30 × H − 5.5 × M| = |30 × 3 − 5.5 × 0| = 90°.
Correct answer: C. 180°
Angle = |30 × H − 5.5 × M| = |30 × 6 − 5.5 × 0| = 180°.
Correct answer: B. 75°
Angle = |30 × H − 5.5 × M| = |30 × 3 − 5.5 × 30| = 75°.
Correct answer: D. 172.5°
Angle = |30 × H − 5.5 × M| = |30 × 9 − 5.5 × 15| = 187.5°; the smaller angle is 360° − that = 172.5°.
Correct answer: C. 100°
Angle = |30 × H − 5.5 × M| = |30 × 7 − 5.5 × 20| = 100°.
