Ans 1:

ADITYA BIKRAM PARIDA from DAV PUBLIC SCHOOL, CUTTACK

b

Ans 2:

AREEN from BOLTON, HYDERABAD
Class : Class 6
Ans is B because 328 tenths will be 32.8 as tenths place is the first place after the decimal point and 4587 thousandths will be 4.587 as thousandths place is the third place after the decimal point. 32.8-4.587=32.800-4.587=28.213. The product of 28.213 and 5 will be 141.065. We are rounding 141.065 to 1 place after the decimal point, which means that we are rounding 141.065 to its nearest tenth, so the answer will be 141.1.
