Directions: Read the following information to answer the question.
Verifying option (1) is very cumbersome. Options (2) and (3) can be verified by expressing the lines
Directions : These questions are based on the data given below.
Solution. From 1 to 100, we have number like 3, 13, 23, 33 etc. which are 10 in number. Then number 30 to 39 have one 3 extra each giving 10 threes.
So, upto hundred, we have 10 + 10 = 20 threes. Since we have 700 pages we have number of 3’s as 7x20 = 140
Then all the 100 numbers from 300 to 399 have one 3 extra each giving a hundred 3’s So totally, 240 threes. Choice (1)
Directions : These questions are based on the data given below.
Solution. Statement I: Since a can take any value including those less than 25, this statement can be true.
Statement II: By observation, we can make out that 2a-b can be less than zero.
Statement III : 3a + 2b
=3(50-k) + 2 (25+l) = 200 – 3k + 2l
This can be grater than 200 since there is no restriction on the value if I where as k<50.
