वर्गकाे क्षेत्रफल.=144cm² भए यसकाे लम्वाइ कति हाेला ?( If area of square =144cm² ,What is length of  its side?)

• area of square =144cm²

  ^{Length of square(l) =?}

  ^{Area of square =(l)2}

  ^{or,144cm2=(l)2}

  ^{or,(l)2=(12cm)2}

  ^l=12cm

• area of square =144cm²

  ^{Length of square =?}

  ^{Area of square =(l)2}

  ^{or,144cm2=(l)2}

  ^{or,(l)2=(11cm)2}

  ^l=11cm

Which are correct answers?

• 
• 
• If C.P.=Rs 300

  S.P=Rs Rs 330

  Find profit or loss

  Solution:Profit =S.P-C.P

  =RS 330-RS300=Rs 30

• If S.P.=Rs 300

  C.P=Rs Rs 330

  Find profit or loss

  Solution:Loss =C.P-S.P

  =RS 330-RS300=Rs 30

• If C.P.=Rs 300

  S.P=Rs Rs 330

  Find profit or loss

  Solution:Profit =S.P+C.P

  =RS 330+RS300=Rs 630

• ख) उत्तर, C.P.=Rs 5000

  S.P=Rs 4500

  C.P>S.P So, loss=?

  Loss=CP-S.P

  =Rs5000-Rs4500

  =Rs500

• ख) उत्तर, C.P.=Rs 5000

  S.P=Rs 4500

  C.P>S.P So, profit=?

  Profit=CP-S.P

  =Rs5000-Rs4500

  =Rs500
