Correct answer is C
Since the salary increases by #36 after every 6 months
: 2 years and 8 months imply an increase of five times only:
36 * 5 → #180
His salary then = initial salary + increment
= 540 + 180
= #720
Answer is C
Find the equation of the line through (5,7) parallel to the line 7x + 5y = 12
5x + 7y = 20
x + 5y = 70
xy = 7
15x + 17y = 90

\(\frac{15}{17}\)
\(\frac{9}{17}\)
\(\frac{8}{15}\)
\(\frac{12}{17}\)
Correct answer is A
Given length of the room = 12m; breadth = 9m and height = 8m.
The room is a cuboid in shape, therefore the length of the diagonal = \(\sqrt{l^2 + b^2 + h^2}\)
= \(\sqrt{12^2 + 9^2 + 8^2}\)
=\(\sqrt{289}\)
= 17m.
The diagonal makes an angle with the diagonal of the floor: \(\sqrt{12^2 + 9^2}\)
= \(\sqrt{225}\)
= 15m
The cosine of the angle that the diagonal makes with the floor (\(\theta\)) = \(\frac{15}{17}\).
