  1. Find the difference between the local value and the face value of digit 4 in numeral 23465?

    1. 396
    2. 404
    3. 0
    4. 800


Answer: (a) 396

Solution: Place value of 7 in tenth place = 70

And the place value of 7 in place of hundred thousand place = 700,000

Hance required product. $$ = 70 \times 700,000 $$ $$ = 49,000,000 $$

  1. Find the sum of the place value of digit 3 in the numeral 43502 and place value of digit 4 in the numeral 604378?

    1. 12,000,000
    2. 7,000
    3. 1,000
    4. 4,003

Place value of digit 6 in 7256013 = 6,000

Hence required product. $$ = 5 \times 6,000 $$ $$ = 30,000 $$

  1. Find the sum and difference of the place value of digit 5 and face value of digit 3 in the numeral 2,503,681?

    1. Sum = 500,003, Difference = 499,997
    2. Sum = 499,997, Difference = 500,003
    3. Sum = 500,000, Difference = 499,999
    4. Sum = 500,006, Difference = 499,994
