Let sister's weight be 100 kg Then brother's weight = (100 + 25) kg = 125 kg Required percentage = (100/125)*100 = 80% 7) Answer: a In these 7 letters, 'R' occurs 2 times, and rest of the letters are different. Hence, number of ways to arrange these letters = {7!} / {2!} = {7×6×5×4×3×2×1} / {2×1} = 2520 8) Answer: d Let the two set sum be A and B and total numbers in each set be n and m respectively. A/n –B/m =6 Also m+n =10, B=56 On solving inadequate data problem take place so answer is (d). 9) Answer: c Total profit = 4/13 * 5% + 9/13 * 10% = 110/13 % 10) Answer: d (P*r*8)/100=1120 P* r = 14000 Two quantities are unknown, so data inadequate. 11) Answer: b By using rule of allegation, CP f the mixture = 22*100/110 = Rs.20

Ratio of quantity = 3:3 = 1:1 Required quantity = (70/1)*1= 70 kg 12) Answer: b According to the question,
