Answer 1

Answer: 498,173.26.

Explanation:

Place value of the 9 in 329,513 = 9,000

9 is 10 times the value of the 9 in 329,513.

Then, place value of 9 in required number = 10x 9,000 = 90,000

from options only 95,826 and 498,173.26 has 9 at ten thousands place. (cancel all other options)

Also, 2 is
`\frac1{10}` the value of the 2 in 7,562.

place value of 2 in required number =
`\frac1{10}*2=0.2`

i.e. place value of 2 in required number 2 tenths

which is in 498,173.26 [place value of 6 is
`\frac1{10}` the value of the 6 in 4.68]

Hence, th required number is 498,173.26.
