D) Rs.5 lakh

Answer:A) Rs.2 lakh

Explanation: Here SP < CP So loss is incurred in this case. According to the formula, Loss= CP -SP = 7-5 = Rs.2 lakh.

Answer:41.66%

Explanation: Given , CP= RS. 60 and SP= RS. 85 Profit = SP-CP = 85 - 60 = RS. 25 According to the formula, Gain % = profit/CP*100 = 25/60*100 = 41.66%.

Answer:18.18 %

Explanation: Given, CP = RS. 550 and SP = RS. 450 Loss = CP-SP = 550 - 450 = RS.100 According to the formula, L oss % = Loss/ CP*100% = 100/550*100 = 18.18 %

Answer: RS. 77

Explanation: Given , CP = RS. 70 and gain = 10% SP = ( 100+ Gain%/100) * CP SP= ( 100 + 10 / 100 ) * 70 = 110 / 100 * 70 =11*7 = RS. 77.
