If an article is sold at a discount of 30% to the marked
price, it makes a loss of 20%. At what per cent discount on the marked price will it break even?Solution
Let the marked price be MP and the cost price be CP. MP × (100 - 30)% = CP × (100 - 20)% MP/CP = 8CP/7 Let the discount on MP to reach break even be d%. MP × (100 - d)% = SP 8CP/7 × (100 - d)% = CP (100 - d)/100 = 7/8 d = 100/8 = 12.5%

What value should come in place of question mark (?) in the following question. (You need not to calcualte the exact value)
?/647 = 226/ ?
(31.9)3 + (34.021)² - (16.11)3 - (42.98)² = ?
123% of 3825 +2745 =11800 - ?
...
115.98 + 109.01 + (√575 - 17) X 20.09 - 204.89 + 38.03 = ?
(168.24 ÷ 23.98) x 19.81 + ? = 176.33
? * 8.21 = (520.12 ÷ 12.98) % of 6800 - 1350.75
