If 25% of 400 + 35% of 1260 + 27% of 1800 = 1020+ x, then the value of x lies between:

6 to 10 0 to 5 11 to 15 16 to 20

6 to 10

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 .
