76.(a) 168÷14=12; 13×4=52; 12+52−30=34.
77.(a) Interest = 52,000−40,000 = ₹12,000 over 3 years; rate = (12,000×100)/(40,000×3) = 10%.
78.(a) The parts total 7+8=15; larger number = 150×8/15 = 80.

82.(a) If CP of 60 articles equals SP of 48 articles, SP/CP per article = 60/48 = 1.25, a profit of 25%.
83.(a) 50% of 200 = 100; 15% of 300 = 45; sum = 145.
84.(a) Combined rate = 1/10; A's rate = 1/15; B's rate = 1/10−1/15 = 3/30−2/30 = 1/30, so B alone takes 30 days.
85.(a) Amount = 70,000×(1.10)² = 84,700; compound interest = ₹14,700.
86.(a) 13(x−10)=6x+14 gives 13x−130=6x+14, so 7x=144, x=144/7=20.57.
87.(a) Area = (22/7)×42² = 22×252 = 5,544 sq cm.
88.(a) Downstream speed = 28+4 = 32 km/h; time = 160/32 = 5 hours.
89.(a) Each term doubles: 25×2=50, 50×2=100, 100×2=200, 200×2=400.
90.(a) A's share is 3 times B's (200% more), so 4 parts = 72,000, giving B's share = ₹18,000.
