Time required for service before overhauling = 2/3h = 40 min in 45 days and time required for service after overhauling =2/3h= 40 min in 60 days Now,LCM of 45 and 60 = 180 days time required for service before overhauling is 180 days = 40 x 4 = 160 min and time required for service before overhauling is 180 days =40 x 3 = 120 min ∴ fraction of time saved = 160 - 120/160 =40/160 = 1/4
Given expression is, 83.04 x 2.01 x 2.1The multiplication value without decimal point = 8304 x 201 x 2 = 3338208Sum of the number of decimal places in the given numbers = 2 + 2 + 1 = 5Now, in the product, the decimal point is marked off to obtain as many places of decimal.Then the answer is 33.38208.
