Profit and Loss<\/h3>\n

In case of profit\u00a0<\/b>
\n25% of \u00a0Cost Price (1\/4 of CP) = 20% of Selling Price (1\/5 of SP)
\nSimilarly 1\/3 of CP \u00a0= 1\/2 of SP<\/p>\n

In case of loss<\/b>
\n25% of \u00a0Selling Price (1\/4 of SP) = 20% of Cost Price (1\/5 of CP)
\nSimilarly 1\/3 of SP \u00a0= 1\/2 of CP<\/p>\n

Estimation<\/h3>\n

That’s the most important technique. This is not a secret that every successful candidate is using this technique during exams.<\/p>\n

Example<\/b> – 112 \u00d7 92
\nSimply 112 \u00d7 9 = 1008
\nAdd a zero 10080 and then add 224 to 10080.
\nAnswer is 10304<\/p>\n

You need to do all the calculations in your brain. Don’t use paper. You need to divide complex calculations in parts and solve it in your brain without paper. That’s how toppers do complex calculations during exams.<\/p>\n

Right now it will be difficult for you to use this method but with practice, you will be able to do any complicated calculation within seconds.<\/p>\n","protected":false},"excerpt":{"rendered":"
