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.

Ans 11:

Class : Class 7
Correct option is not given.If Initial time is 4:45, Time taken = 2 hr 15 mins, Actual final time = 7:00 then Clock will show = 7:30 as clock is slower by 30 mins.

Can somebody report an error? Reason: the clock was not accurate. the hr hand was at 4 when the minute hand was at 9! But the hour hand is supposed to be between x ad x 1(x is hour) if y(minute hand number) is grater than 6. But the picture does not follow that rule and thus the picture is wrong.

The triangle's value is the seventh multiple of seven which is 49.So we can do 49 - 4 to get the square's value.49 - 4 is 45,so the value of the square is 45.Now 45 divided by 15 is 3 ,so the answer is B
