Cost price (CP) = Rs. 1, 50, 000
Selling price (SP) = Rs. 75, 000
Loss = (CP - SP) 1, 50, 000 – 75, 000 = Rs. 74, 500
Loss Percentage = LossCP x 100
= 74,5001,50,000 x 100 = 49.67%
Faulty phones = 213 % or 73%
Defective in packaging = 413 % or 133 %
Faulty and defective phones out of total phones is given by:
73 % of 1200 + 133 % of 1200 = (73x100 + 133x100) x 1200 = 80 phones.
Non faulty and non defective = 1200 – 80 = 1120 phones.
Let price = Rs. x
Reduced price = Rs. 34x
Increased price = 65 * 34x = 910x
Lcm of 2, 4, 6, 8, 10, 12 = 120secs => 2min
Toll in 30mins = 30/2 => 15 times.
