Question
A boy goes to school with a speed of 50 km/h and comes
back with a speed of 30 km/h. find his average speed?Solution
Since the distance travelled by a boy (going to school and coming back from school) is equal. So, average speed = 2xy/(x + y) Average speed = (2 x 50 x 30)/(50 + 30) Average speed = (2 x 50 x 30)/80 = 37.5 km/hr
Statements: J < K = L ≥ M ≥ P; F ≥ K < G
Conclusion I. J < G II.F ≥ P
...Statement: T > U = V < W > X; Y ≤ H < S; X > Z > S
