1:30:34, students this question was damn easy, u just had to compare the ratio, although sir saad method was also good but for 1 mark dont waste such long time on that question, u can just calculate area of parallelogram 0ABC using formula b multiply h u will get the area which is "ac", then similarly calculate area of parallelogram OPQR u will get area 10ac after simplification, u can clearly observe thaat the ratio is 1 is to 10

Sir for the last part we can do that (5*4)/(1*2) which will be 20/2 and hence 1/10 it's more easier
