Directions (1-5): Read the given information carefully and answer the questions that follows.
Table shows the three types of waves (in percentage) which together constitutes 35% of the sun rays received in a minute and the paragraph gives the information about remaining of the sun rays received in that minute. Total units of sun rays received in 1 minute= 3600 units.
There are five types of rays i.e. IR rays, UV rays, Gamma rays, X rays and β rays. Ratio of units of Gamma rays received to UV rays received is 2: 3. Units of X rays received is 100% more than units of IR rays received. The amount by which Gamma rays is more than that of IR rays is 25% of the Alpha rays received in that minute. β rays received is 50% of the IR rays received.
Q2. The amount of UV rays received in 5 mins is how many times the amount of IR rays received in 2 mins?
(a) 4.25 times
(b) 4.15 times
(c) 4.5 times
(d) 4.75 times
(e) None of these
Q3. If 3600 units of sun rays received in one minute were after the reflections of 55% of the sun rays by the ozone layers. What would be the amount of Gamma rays received in one minute, if the ozone layer were to disappear completely?
(a) 960 units
(b) 1050 units
(c) 920 units
(d) 880 units
(e) 900 units
Q4. The amount of Micro waves received in 5 minutes is how much more/less than the amount of Alpha waves received in 4 minutes?
(a) 1538 units
(b) 1544 units
(c) 1536 units
(d) 1542 units
(e) 1548 units
