let x be the number
so,
70% of x - 57% of x = 338
70x/100 - 57x/100 = 338
13x = 338×100
x= 33800/13
2600
now
51% of 2600 would be
=1326
hope this will help you

मान लो की वो संख्या है x.
तो फिर, प्रश्न के मुताबिक;
(70\% \: of \: x)- (57\% \: of \: x) = 338 \\  = >  \:  (\frac{70}{100}  \times x) - ( \frac{57}{100}  \times x) = 338 \\  =  >  \:  \frac{70}{100} x -  \frac{57}{100}x = 338 \\  =  >  \:  \frac{(70x - 57x)}{100}  = 338 \\  =  >  \:  \frac{13}{100}x = 338 \\  =  >  \: x = 338 \times  \frac{100}{13}   \\  =  >  \: x =  \frac{33800}{13}  \\  =  >  \: x = 2600
तो वह संख्या 2600 है
तो उसका 51% होगा =
51\% \: of \: x  \\  =  \frac{51}{100}  \times x \\ on \: putting \: the \: value \: of \: x \\  =  \frac{51}{100}  \times 2600 \\  = 51  \times 26 \\  = 1326
