Quote: How many digits will be there to the right of the decimal point in the product of 95.75 and 0.02554 ?
A. 5 B. 6 C. 7 D. 8 E. None of these Total decimal places to the right = 7 However, 95.75 * 0.02554 would give the 7th demimal place as zero (because 5*4=2 0). Since we don't count the last number if its zero, then there would only be 6 decimal points to the right. Hence, answer is option B

95.75 * 0.02554 = 95.75 * 25.54 * (1/1000) = (383/4) * (1277/50) * (1/1000) = (383*1277)/(200,000) = (383*1277*5)/(1,000,000)
Estimate: = (383*1277*5)/1,000,000 = (400*1250*5)/1,000,000 = 2,500,000/1,000,000 = 2.500000
So, it is about 6 decimal points
Answer is (B)

How many digits will be there to the right of the decimal point in the product of 95.75 and 0.02554 ? A. 5 B. 6 C. 7 D. 8 E. None of these Both the two numbers have 2 and 5 digits respectively after decimal which after multiplication would result in 5 or greater number of digits. 0.75 can be written as 3/4 where 0.02554 not being a multiple of 4 results in 6 digits when divided by 4. Answer (B).

None of these Note that we are multiplying 9575 with 2554 (and with total 7 decimal places). 2554 is divisible by 2 but not by 4. 9475 is not divisible by 2 but it is divisible by 5. So when we multiply 9575 with 2554, we will end with one 0. When we move 7 places back the 0 will be ignored and we will have 6 non zero digits after the decimal. Answer (B)
