Answers & Solutions   1 .     Answer : Option C Explanation : Total no.of soap cakes produced per day of brand P by all the three companies = 400 x $10\over 100$ + 300 x $40 \over 100$ + 500 x $20\over 100$ = 260 Total no.of soap caked produced per day of brand C by all the three companies = 400 x $60\over 100$ x 300 x $40\over 100$ + 500 x $30\over 100$ = 510 Total no.of soap cakes produced per day of brand S by all the three companies = 400 x $30\over 100$ + 300 x $20 \over 100$ + 500 x $50 \over 100$ = 430 Hence the least no.of soap cakes produced per day by all the three companies is of brand P. 2 .     Answer : Option A Explanation : $1\over 10$ x Total no.of cakes produced by the all the companies / day = $1\over 10$ x 260 + 510 + 430 = $1200 \over 10$ = 120 Company X produced 120 S cakes per day. 3 .     Answer : Option C Explanation : Number of cakes of brand P produced day by Y = 120 Number of cakes of brand C produced per day by Z is 150. Hence required ratio = $120\over 150$ = $4\over 5$ = 4 : 5 4 .     Answer : Option D Explanation : The number of cakes produced by X, Y, Z are now 400, 400, 500 respectively. The number of cakes of brand P produced by all the companies after this change is = 0.1 × 400 + 0.4 × 400 + 0.2 × 500 = 300 And new total becomes, (400 + 400 + 500) = 1300 the required percentage = $300 \over 1300$ x 100 $\cong$ 23 % 5 .     Answer : Option C Explanation : 6 .     Answer : Option B Explanation : To find the percentage increase (or decrease), divide the numerical change by the original amount 7 .     Answer : Option B Explanation : Calculating 10 percent of the sales for each years , 10% of sales (crores), Earning (crores) 8 .     Answer : Option D Explanation : Total exp = 45 + 40 = 85 cr Total inc = 35 + 50 = 85 cr no profit no loss 9 .     Answer : Option D Explanation : Income of A in 1999 = 37.5 x $100 \over 100 + 10$ cr Expenditure in 1999 = 37.5 x $100 \over 110$ x $100 \over 120$ = 28.41 cr 10 .     Answer : Option B Explanation : Expenditure of G in 1999 = 45 x $100 \over 120$ Income of G in 1999 = 45 x $100 \over 120$ x $110 \over 100$ = 41.25 cr.
