Calculate 993 × 98 with different bases (1000 and 100).
  • a)
    97,314
  • b)
    97,324
  • c)
    97,334
  • d)
    97,344
Correct answer is option 'A'. Can you explain this answer?

Understanding the Calculation
To compute 993 × 98, we can break it down using the bases of 1000 and 100 for easier calculations.
Step 1: Using Base 1000
- Round 993 to 1000 and adjust for the difference:
- 993 is 7 less than 1000.
- Calculate using 1000:
- 1000 × 98 = 98,000
- Adjust for the difference:
- 98,000 - (7 × 98) = 98,000 - 686 = 97,314
Step 2: Using Base 100
- Round 993 to 1000, but focus on tens:
- 993 is 3 less than 1000.
- Calculate using 100:
- 990 × 98 = 97020 (990 is the nearest lower multiple of 10).
- Adjust for the difference:
- 97020 + (3 × 98) = 97020 + 294 = 97,314
Final Result
Both methods yield the same result:
- Therefore, 993 × 98 = 97,314.
Conclusion
- The correct answer is option 'A': 97,314.
This demonstrates how breaking down numbers and using different bases can simplify multiplication and confirm accuracy in calculations.

Calculate 432 × 999 using the "All from 9 and the Last from 10" method.

Vp Classes answered
432 × 999 = 432 × (1000 - 1). LHS: 432 - 1 = 431. RHS: Apply sutra to 432 (4 from 9 = 5, 3 from 9 = 6, 2 from 10 = 8) = 568. Combine: 431|568 = 431,568. So, 432 × 999 = 431,568.

Multiply 67 × 63 using the complementary numbers method (sum of units digits is 10).
  • a)
    4,221
  • b)
    4,211
  • c)
    4,231
  • d)
    4,201
Correct answer is option 'A'. Can you explain this answer?

Praveen Kumar answered
First digit is 6 for both, 7 + 3 = 10. LHS: 6 × 7 (one more than 6) = 42. RHS: 7 × 3 = 21. Combine: 42|21 = 4,221. So, 67 × 63 = 4,221.

Using the vertically and crosswise method, find (2x + 3)(3x + 4).
  • a)
    6x² + 17x + 12
  • b)
    6x² + 16x + 12
  • c)
    6x² + 17x + 10
  • d)
    6x² + 16x + 10
Correct answer is option 'A'. Can you explain this answer?

EduRev Class 6 answered
Vertical: 3 × 4 = 12. Crosswise: 2 × 4 + 3 × 3 = 8 + 9 = 17x. Vertical: 2 × 3 = 6x². Combine: 6x² + 17x + 12. So, (2x + 3)(3x + 4) = 6x² + 17x + 12.

Find 495 × 498 using the sub-base method with a sub-base of 500.

    246,510
  • b)
    246,500
  • c)
    246,490
  • d)
    246,520
Correct answer is option 'A'. Can you explain this answer?

Coachify answered
Sub-base is 500 (5 × 100). Write 495|-05 and 498|-02. LHS: 495 - 2 = 493 (or 498 - 5 = 493). RHS: -05 × -02 = 10. Combine: 493 × 5 = 2465, then 2465|10 = 246,510. So, 495 × 498 = 246,510.

Calculate 96 × 97 using the same base method (base 100).
  • a)
    9,312
  • b)
    9,302
  • c)
    9,322
  • d)
    9,292
Correct answer is option 'A'. Can you explain this answer?

Gunjan Lakhani answered
96|-04, 97|-03. Cross-subtract: 96 - 3 = 93 (or 97 - 4 = 93). Vertical: -04 × -03 = 12. Combine: 93|12 = 9,312. So, 96 × 97 = 9,312.

Multiply 887 × 9999 using the "All from 9 and the Last from 10" method.
  • a)
    8,869,113
  • b)
    8,869,123
  • c)
    8,869,133
  • d)
    8,869,143
Correct answer is option 'A'. Can you explain this answer?

Base 10000. LHS: 887 - 1 = 886. RHS: Apply sutra to 0887 (0 from 9 = 9, 8 from 9 = 1, 8 from 9 = 1, 7 from 10 = 3) = 9113. Combine: 886|9113 = 8,869,113. So, 887 × 9999 = 8,869,113.

Using the doubling method, calculate 43 × 8.
  • a)
    344
  • b)
    334
  • c)
    354
  • d)
    324
Correct answer is option 'A'. Can you explain this answer?

Coachify answered
43 × 8 = 43 × 2 × 2 × 2. First, 43 × 2 = 86. Then, 86 × 2 = 172. Finally, 172 × 2 = 344. So, 43 × 8 = 344.

Using the vertically and crosswise method, multiply 24 × 13.
  • a)
    312
  • b)
    302
  • c)
    322
  • d)
    292
Correct answer is option 'A'. Can you explain this answer?

Vertical: 4 × 3 = 12 (write 2, carry 1). Crosswise: 2 × 3 + 4 × 1 = 6 + 4 = 10 + 1 = 11 (write 1, carry 1). Vertical: 2 × 1 = 2 + 1 = 3. Combine: 3|1|2 = 312. So, 24 × 13 = 312.

Using the making halves method, find 78 × 50.
  • a)
    3,900
  • b)
    3,850
  • c)
    3,800
  • d)
    3,950
Correct answer is option 'A'. Can you explain this answer?

Praveen Kumar answered
78 × 50 = (78 × 100) ÷ 2. First, 78 × 100 = 7,800. Then, 7,800 ÷ 2 = 3,900. So, 78 × 50 = 3,900.

Using the sub-base method, calculate 208 × 196 with a sub-base of 200.
  • a)
    40,768

    40,758
  • c)
    40,748
  • d)
    40,738
Correct answer is option 'A'. Can you explain this answer?

Rahul Kumar answered
Sub-base is 200 (2 × 100). Write 208|+08 and 196|-04. LHS: 208 - 4 = 204 (or 196 + 8 = 204). RHS: 08 × -04 = -32. Combine: 204 × 2 = 408, then 408|-32 = 40800 - 32 = 40,768. So, 208 × 196 = 40,768.

  • a)
    26,196
  • b)
    26,186
  • c)
    26,176
  • d)
    26,166
Correct answer is option 'A'. Can you explain this answer?

Subset Academy answered
Write 2|3|6. Second: 2 + 3 = 5. Third: 2 + 3 + 6 = 11 (carry 1). Fourth: 3 + 6 + 1 = 10. Adjust: 2|5 + 1|11|6 = 2|6|1|6. So, 236 × 111 = 26,196.

    11,232
  • b)
    11,222
  • c)
    11,242
  • d)
    11,212
Correct answer is option 'A'. Can you explain this answer?

108|+08, 104|+04. Cross-add: 108 + 4 = 112 (or 104 + 8 = 112). Vertical: 08 × 04 = 32. Combine: 112|32 = 11,232. So, 108 × 104 = 11,232.
