Section C:

76.(a) 240÷16=15; 18×3=54; 15+54−40=29.

77.(a) Interest = 78,000−60,000 = ₹18,000 over 3 years; rate = (18,000×100)/(60,000×3) = 10%.

78.(a) The parts total 15+19=34; larger number = 238×19/34 = 133.

79.(a) Profit = 2,400−1,920 = ₹480; profit percentage = (480/1,920)×100 = 25%.

80.(a) The first seventy-five natural numbers sum to 2,850; average = 2,850/75 = 38.

81.(a) Speed = 480 m / 48 s = 10 m/s = 10×18/5 = 36 km/h.

82.(a) If CP of 85 articles equals SP of 68 articles, SP/CP per article = 85/68 = 1.25, a profit of 25%.

83.(a) 100% of 90 = 90; 25% of 240 = 60; sum = 150.

84.(a) Combined rate = 1/15; A's rate = 1/25; B's rate = 1/15−1/25 = 5/75−3/75 = 2/75, so B alone takes 75/2 = 37.5 days.

85.(a) Amount = 1,20,000×(1.05)² = 1,32,300; compound interest = ₹12,300.

86.(a) 18(x−15)=11x−30 gives 18x−270=11x−30, so 7x=240, x=240/7.

87.(a) Area = (22/7)×77² = 22×847 = 18,634 sq cm.

88.(a) Downstream speed = 36+9 = 45 km/h; time = 270/45 = 6 hours.

89.(a) Each term doubles: 50×2=100, 100×2=200, 200×2=400, 400×2=800.

90.(a) A's share is 4 times B's (300% more), so 5 parts = 2,00,000, giving B's share = ₹40,000.

Section D:
