Solution

The correct option is D 1080
$\begin{matrix} F a c i l i t i e s & N o . o f V i l l a g e r s H a v e o n l y a d e q u a t e w a t e r s u p p l y & \frac{25}{100} \times 1800 = 450 H a v e o n l y p r o p e r e l e c t r i c s u p p l y & \frac{15}{100} \times 1800 = 270 H a v e o n l y p r o p e r e d u c a t i o n f a c i l i t i e s & \frac{7}{100} \times 1800 = 126 H a v e o n l y t e l e c o m m u n i c a t i o n s e r v i c e s & \frac{12}{100} \times 1800 = 288 H a v e w a t e r a n d e l e c t r i c s u p p l y & \frac{6}{100} \times 1800 = 108 H a v e p r o p e r w a t e r s u p p l y, e l e c t r i c s u p p l y a n d h e a l t h c a r e s e r v i c e s & \frac{8}{100} \times 1800 = 144 H a v e p r o p e r e l e c t r i c s u p p l y t e l e c o m m u n i c a t i o n a n d h e a l t h c a r e s e r v i c e s & \frac{5}{100} \times 1800 = 90 H a v e a l l t h e f a c i l i t i e s & \frac{6}{100} \times 1800 = 108 \end{matrix}$
Number of villages with proper supply of electricity = $270 \div 108 \div 144 \div 90 \div 108 = 720$
Number of villages not having proper electric supply = 1800 - 720 = 1080
