first discount is 10%, the second is.
एक पुस्तक का सूची मूल्य (अंकित मूल्य) रु 160 है। मोनू इसे दो क्रमागत जिसमें एक 10% है, प्राप्त कर रु 122.40 में खरीदता
है तो दूसरी छूट क्या है?​

Answer 1

Answer:

LP - Rs. 160

Discount of 10% on LP = 10/100*160

= 16 Rs.

Discounted Price = 160 - 16 = 146 Rs.

Successive discount price = 146 - 122.40 = 23.60

Successive discount =

x/100*146 = 23.60

146x = 236

x = 236/146

= 118/123

0.96% is the second discount.
