B 22000 mL 8/29
C 10000 mL 7/27
D 25000 mL 9/36


Ans not understood... I doubt if the ans is correct.

Ans 1:

AREEN from BOLTON, HYDERABAD
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.

Ans 7:

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.
