\sf{✙Let:-}

 \sf \red {?  \: be \: \: x }

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

\sf{✙Solution:-}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

 \sf{77\% \: of \: 150 \:  + \: 37.5\% \: of \: 260 \:  = } \sf \red {\: ?\% of \: 284 }

 \sf{ \frac{77}{ \cancel1 \cancel0 \cancel0} \: \times \:  \cancel1 \cancel5 \cancel0 \:  +  \frac{37.5}{\cancel1 \cancel0 \cancel0}   \times \cancel2\cancel6\cancel0  =} \sf \red{  \:   \frac{x}{\cancel1 \cancel0 \cancel0}  \times  \: \cancel2\cancel8\cancel4 }

 \sf{ \frac{77}{2} \times 3 +  \frac{37.5}{5} \times 13 = }\sf \red{  \frac{71x}{25}   }

 \sf{ \frac{231}{2}+  \frac{ \cancel37.5}{ \cancel5} \times 13 =  } \sf \red{\frac{71x}{25}   }

 \sf{ 115.5+  7.5 \times 13 = } \sf  \red{ \frac{71x}{25}   }

 \sf{ 115.5+  97.5=}  \sf  \red{\frac{71x}{25}}

 \sf{213 = } \sf \red{ \frac{71x}{25} }

 \sf{213 \times 25 =} \sf \red{ 71x }

 \sf{5325 =} \sf \red{ 71x }

 \sf{ \frac{ \cancel5325}{ \cancel71}  =} \sf \red{ x }

 \sf \red{ 75 = x }

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

\sf{Answer \:  is \: } \sf \red{ 75}
