Section C:
76.(a) 144÷12=12; 11×4=44; 12+44−18=38.
77.(a) Interest = 41,600−32,000 = ₹9,600 over 3 years; rate = (9,600×100)/(32,000×3) = 10%.
78.(a) The parts total 8+9=17; larger number = 170×9/17 = 90.
79.(a) Profit = 1,350−1,080 = ₹270; profit percentage = (270/1,080)×100 = 25%.
80.(a) The first forty natural numbers sum to 820; average = 820/40 = 20.5.
81.(a) Speed = 240 m / 24 s = 10 m/s = 10×18/5 = 36 km/h.
82.(a) If CP of 50 articles equals SP of 40 articles, SP/CP per article = 50/40 = 1.25, a profit of 25%.
83.(a) 35% of 200 = 70; 20% of 250 = 50; sum = 120.
84.(a) Combined rate = 1/30; A's rate = 1/50; B's rate = 1/30−1/50 = 5/150−3/150 = 2/150 = 1/75, so B alone takes 75 days.
85.(a) Amount = 50,000×(1.04)² = 54,080; compound interest = ₹4,080.
86.(a) 12(x−8)=6x+12 gives 12x−96=6x+12, so 6x=108, x=18.
87.(a) Area = (22/7)×14² = 22×28 = 616 sq cm.
88.(a) Downstream speed = 22+3 = 25 km/h; time = 100/25 = 4 hours.
89.(a) Each term doubles: 20×2=40, 40×2=80, 80×2=160, 160×2=320.
90.(a) A's share is 3 times B's (200% more), so 4 parts = 1,20,000, giving B's share = ₹30,000.
