Ganita Manjari Part 1, Chapter 8: 16 MCQs with answers

To consolidate fluency, reasoning, and problem solving

The chapter is a consolidation chapter that strengthens numerical fluency, logical reasoning, and step-by-step problem solving rather than introducing one isolated new topic.

Addition

Addition combines quantities. Subtraction finds difference or remainder, multiplication handles repeated groups, and division shares equally.

Chosen the wrong operation for the situation

'How many more' signals a difference, so subtraction is needed. Writing a multiplication sign is a wrong-operation error, which is the classic translation mistake in this chapter.

Read, plan, compute, check, answer

The five-step habit is read, plan, compute, check, answer. It is the most transferable skill in the chapter and applies to all later mathematics.

True

Chapter 8 of Ganita Manjari Part 1 is a consolidation chapter that strengthens fluency, reasoning, and multi-step problem solving rather than introducing a single isolated new topic.

95 pencils

Selling removes pencils, so subtract: $240 - 85 = 155$, then $155 - 60 = 95$. Verification: $85 + 60 = 145$ sold, and $240 - 145 = 95$.

It is where speed, accuracy, and confidence are built

Consolidation chapters are where speed, accuracy, and confidence are actually built. Students who treat them as 'easy' and rush through lose the foundation later topics depend on.

Check

The check step would have caught the missing subtraction. Verification by estimation or reverse operation detects exactly this kind of slip before it costs marks.

I, II and III are all correct

All three statements are correct. Direct problems build speed, word problems build judgement, and both types appear in the chapter.

Both A and R are true, and R explains A

Reading twice is recommended precisely because it reduces wrong-operation errors, so R is the correct explanation of A.

The units that give the number meaning

Answers must include correct units where applicable. Without units, the number 95 does not tell you what it counts.

Estimation — the answer cannot exceed the total

Estimation is a free error-detector. If 240 items existed and 300 remain, the answer is impossible, so the slip is caught immediately without recomputation.

Either works; both give the same verified result

Both approaches are valid: $240 - 85 - 60 = 95$ and $240 - (85 + 60) = 95$. The chapter's verification habit confirms they agree, which is itself a check on the answer.

Each stage prepares the mental muscle for the next

The chapter's structure is deliberate: recall refreshes the foundation that guided examples, practice sets, and application problems all build on. Skipping it removes the base the later stages stand on.

Speed increases slips; accuracy should come first

The chapter explicitly says accuracy beats speed: a fast wrong answer scores zero. Speed comes naturally once the method is automatic, so rushing increases the very slips the student wants to avoid.

'Shared equally' → division

'Shared equally' signals division. 'How many more' signals subtraction, 'repeated groups' signals multiplication, and 'total combined' signals addition.
