Option A)

Ans 3:

Class : Class 6
Ans is A because the answer of question (A) will be 20000 ml because 40 l-20 l=20 l. Now convert 20 l to ml, which is 20000 ml, or, you can say that 20 l and 40 l will be 20000 ml and 40000 ml, respectively. Now do 20000 ml-40000 ml=20000ml. answer of question (B) will be 7/26 by adding the capacity of petrol of April, May, June, July and August, which will be 10 l+20 l+ 25 l+35 l+40 l=130 l. In July, the capacity of petrol used was 35 l, so in fraction, it will be 35 l/130 l. Now simplify the fraction, which will be 7 l/26 l.

c127.1 plus 12.1 = 139.2

Ans 2:

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.

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.

Ans 3:

Class : Class 4
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.

Sorry I meant I chose option D) 6:30 p.m. not C.

Ans 8:

Class : Class 4
Ya. I decided to choose option C though even though I realized it was 7:30 p.m . I mean if the clock time was true in the picture, the answer would be 7:00 p.m. They did not mention whether the clock time was true or not

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.

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
