    Explanation

    C.P. of 50 kg of wheat @Rs. 13.4/kg = 50 × 13.4 = Rs. 670 C.P. of 40 kg of wheat @Rs. 16.75/kg = 40 × 16.75 = Rs. 670 Total C.P. of 90 kg of wheat = 670 + 670 = Rs. 1340 As per the given information, Mohan wants to earn a profit of 25%. ∴25=Total  S.P.    −  13401340  ×100\therefore 25 = \frac{{{\rm{Total\;S}}.{\rm{P}}.{\rm{\;\;}} - {\rm{\;}}1340}}{{1340}}\; \times 100 ⇒ Total S.P. = Rs. 1675 ⇒ Selling price of 90 kg of wheat = Rs. 1675 ⇒ Selling price of wheat per kg = 1675/90 = Rs. 18.61
