Chiranjib kar from MOUNT LITERA ZEE SCHOOL, JAJPUR
Subject :IMO    Class : Class 5

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.
