If 2A = 3B = 7C = 42, then what is the value of A × B ÷ C?

If $$ {x+{1\over 16x}}=1 $$, then $$ {64x^{3}+{1\over 64x^{3}}}$$ will be:

Four runners started running simultaneously from a point on a circular track. They took 200 seconds, 300 seconds, 360 seconds and 450 seconds to complete one round. After how much time do they meet at the starting point for the first time? 

Direction : What should come in place of the question (?) in the following question.

35% of 430 + ? % of 360 = 276.5

Directions:Study the following table carefully to answer these questions:

Percentage of Marks obtained by six students in six subjects

What is the ratio between total marks obtained by D in Biology, Maths and English together and the total marks obtained by F in these subjects together respectively?

Direction: Given bar graph shows the number of plain books and lined books (in hundreds) available at three different stores and the table shows the percentage of total books (Plain + lined) that was sold by different stores.

The selling price of each plain books and lined books sold by store B is Rs. 250 and Rs. 175 respectively. Then, find the total amount earned by store B on selling these books if 60% of lined books are sold by the store?
