Question
If the sum of three numbers is zero, then which of the
options below will always be equal to the value of the sum of the cubes of those numbers?Solution
ATQ- a+b+c = 0 a3+b3+c3 =? Use of this formula- a3+b3+c3-3abc =(a+b+c) (a2+b2+c2-ab-bc-ca) a3+b3+c3-3abc= 0(a2+b2+c2-ab-bc-ca) a3+b3+c3-3abc=0 a3+b3+c3 =3abc
19.89% of 449.67 + 14.67% of 299.89 - 9.89% of 99.79 = ?
`(sqrt(960.87)xx9.932+sqrt(629.998)xx26.385)/(sqrt(1028.902)xx4.977)=?`

1299.999 ÷ 325.018 × 24.996 = ?
What approximate value should replace the question mark?
99.95 − √529 × 3 + 1439.80 ÷ 12.02 = ?
619.97 ÷ 20.01 X 124.99 ÷ 24.91 = ?
124% of 620.99 + 11.65% of 1279.23 = ?
What approximate value should replace the question mark?
9.96% of 1200.10 − 25% of 4800 = ? − 7000.20
