47.0 < c =" a/b;" 1 =" c," b =" a/a-1"> --No----(is wt1 > wt.2)--No--(select box2) Yes Yes select box 3 select box 1 ------------------------------------------------ select two balls is wt.ball.1 = wt.ball.2 --- No -- is wt.ball.1> wt.ball.2 -- No Yes Yes ball.2 ball.3 is ball.1 is is heaviest heaviest heavist so there will be some blank in this flow chart and u have to fill up the blanck with correct option. Q2) there are red and black balls. if ball is red then one point. ifball is black and previous ball is red then two points. For winning u have to get seven points. No point for same color consecutive balls. ----------- select ball is ball red --- Yes -- Is previous --No--- ball red No p=p+1 No is previous ball black --No----------- p=p+2 --count= count+1 Yes ---is ball left No point Yes No end -------------------------------------------- Q3) Classify objects in class A, class B and scrap. for classfing uhave to do diffrent test such as weight, material etc. and Flow char forthis ques. will be there along with some blanks. Q4) There is production process in which action depend on temprature andpressure. and there are temp. and press. controls. Q5) find max. and min. of the 12 nos. there will array and u have toarrange the numbers in assending/ descending order and find out max. andmin. Q6) diffrent age group are given and also diffrent salary slabs aregiven. so depending on the salary group as well as his group u have tofill the person in particular class. (ques. is not in exact form.)
