SP of a table at a gain of 5%=CP + gain% of CP
2142=CP + 5% of CP
2142=CP (1 + 5/100)
2142=21/20 CP
2142×20/21=CP
Rs240=CP
SP of a table at a gain of 10%=CP+gain% of CP
=240+10% × 240
=240 (1 + 10/100)
=240 ×110/100
=Rs 264
hope it helps you!☺

Manyampujitha: I got answer as 204

1Twinkle1: ok I will try it again

1Twinkle1: Let cost price of table = x , So we get

x + 5% of x = 2142

⇒x+ 5 x100 = 2142⇒x+ x20 = 2142⇒20 x + x20 = 2142⇒21 x20 = 2142⇒x = 2142 × 2021⇒x = 102 × 20⇒x =2040

1Twinkle1: at last we get an answer 2040

1Twinkle1: SP of a table at a gain of 10%=2040 + 10% of 2040

1Twinkle1: and this way you will get the answer

1Twinkle1: sorry for giving u a wrong answer
