If 25% of 400 + 35% of 1260 + 27% of 1800 = 1020+ x, then the value of x lies between:
Answer & explanation
Correct answer: option 1
25% of 400 + 35% of 1260 + 27% of 1800 = 1020+ x
\(\frac{25}{100}\) × 400 + \(\frac{35}{100}\) × 1260 + \(\frac{27}{100}\)× 1800 = 1020 + x
100 + 441 + 486 = 1020 + x
1027 = 1020 + x
x = 7
So , x lies b/w 6 to 10 .
