Answer 1

Answer:

9. Here,

• Selling price = ₹1128
• Loss% = 6%
• So, Cost price = SP *100/100-loss% = 1128*100/100-6 = 1128*100/94 = 12*100 = ₹1200

10.First draw a line of 5.5cm and name YZ now on Y point draw a angle of 75° then mark a point X which start from point Y of 6 cm and end at point X.Now join X point to Z point.

11. Here, principal = ₹12000

• Rate = 7.5%
• Time = 3.5 years
• So, Simple Interest = P*R*T /100 = 12000*7.5*3.5/100 = 120*7.5*3.5 = ₹3150
• Amount = Principal + SI = ₹12000+3150 = ₹15150
