Now, the percentage figures of say, 70%, 95% and so on, we'll use the decimal format of the, thus 70% is just 70/100 or 0.7 and 95% is just 95/100 or 0.95 and so on
so
whatever "x" and "y" amounts are, we know, they must add up to 160 pints
thus x + y = 160
now, whatever the concentrated amount of solute in the mixture, we know they must add up to 160*0.85 or 136
thus 0.7x + 0.95y = 136
thus
solve for "x", to see how much of the 70% pure juice will be needed
what about "y"? well, y = 160 - x
so
whatever "x" and "y" amounts are, we know, they must add up to 160 pints
thus x + y = 160
now, whatever the concentrated amount of solute in the mixture, we know they must add up to 160*0.85 or 136

Answer: Option 'E' is correct.
Step-by-step explanation:
Since we have given that
Let the total number of gongs be 'g'.
Number of ten inch gongs = 18
Let the number of 12 inch gongs be 'x'.
Let the number of 15 inch gongs be 'y'.
so, equation would be
Half of the gongs are tiger gongs is given by
Half of the 12 inch gongs are not tiger gongs
so, number of tiger gongs which is of 12 inch =
Among the tiger gongs, there are equal numbers of ten inch, twelve inch and fifteen inch.
Half of the gongs are of 15 inch is given by
Since we have
so, According to question, it becomes,
Hence, Option 'e' is correct.
