10 ×x+ 10010
10 ×x+ 10010
10 ×x+ 10010 ×x+ Rs 1500=x ⇒
10 ×x+ 10010 ×x+ Rs 1500=x ⇒ 10080x
10 ×x+ 10010 ×x+ Rs 1500=x ⇒ 10080x
10 ×x+ 10010 ×x+ Rs 1500=x ⇒ 10080x + Rs 1500=x⇒x−4x
10 ×x+ 10010 ×x+ Rs 1500=x ⇒ 10080x + Rs 1500=x⇒x−4x
10 ×x+ 10010 ×x+ Rs 1500=x ⇒ 10080x + Rs 1500=x⇒x−4x = Rs 1500 ⇒
10 ×x+ 10010 ×x+ Rs 1500=x ⇒ 10080x + Rs 1500=x⇒x−4x = Rs 1500 ⇒ 5 = Rs 1500⇒x=1500×5= Rs 7500
