A goods truck travels from a place at a certain time and at fixed speed. After 6hrs another truck leaves the same place and move in same direction of uniform speed of 90kmph. The truck catches up the goods truck in 4hrs. Find the speed of the goods truck ?
Let the speed of goods truck be 'p' kmph Distance covered by goods truck in 10hrs (4+6) = Distance covered by other truck in 4 hrs. 10p = 4 x 90 p = 36kmph. Therefore, the speed of the goods truck is p = 36 kmph.
According to the National Agricultural Aviation Society (NAAS), without the use of crop protection products to control insects, weeds, and diseases, crop yields per acre will drop by more than 50 percent. The first aerial appligreion of insecticide occurred in 1921, and it was a huge success. By contrast, in today's economy all aircraft that are classified as aerial appligreors do more than just apply insecticide; today, they also spread seed and apply fertilizer.
From the information given above it CANNOT be validly concluded that
A) In today's economy, if an aerial appligreor is used, then it will be able to spread seed and to apply fertilizer
B) according to the NAAS, if crop yields per acre never drop by more than 50 percent, then crop protection products have been used to control insects, weeds, and diseases
C) in today's economy, any aircraft that cannot be used to apply fertilizer cannot be classified as an aerial appligreor
D) according to the NAAS, if crop yields per acre drop by more than 50 percent, then crop protection products have not been used to control insects, weeds, and diseases.

The average of the ages of Sushanth, Krish and Rishi is 43 years and the average of the ages of Sushanth, Rishi and Rohit is 49 years. If Rohit is 54 years old, what is Krish's age ?
Let present ages of Sushanth = w, Krish = x, Rishi = y and Rohit = z , then w + x + y = 43 x 3 = 129 ---(i) and w + y + z = 49 x 3 = 147 ---(ii) Subtracting (i) from (ii), (w+y+z) - (w+x+y) = 147 - 129 , z - x = 18 ---(iii) Given Rohit's age=z=54, so from (iii), x = 54 - 18 = 36. Therefore, Krish age is 36 years.
