Question
In January, 'A' earned Rs. 16,000 and spent 75% of it.
The following month, his income rose by Rs. 4,000, and his savings went up by Rs. 2,000. Calculate 'A's expenditure in February.Solution
Savings of ‘A’ in January = 0.25 × 16000 = Rs. 4000 Savings of ‘A’ in February = 4000 + 2000 = Rs. 6000 Income of ‘A’ in February = (16000 + 4000) = Rs. 20000 Expenditure of ‘A’ in February = 20000 – 6000 = Rs. 14000
(408 × 680)÷(20% of 680) = (250 × 260)÷ 10 + ? – 4500
If x + y + z = 7, x² + y² + z² = 85 and x³ + y³ + z³ = 842, then the value of √3 xyz is:
...If x = (2+√3)/(2-√3), y = (2-√3)/(2+√3)
Then find out the value of (x²+y²-xy)/(x²+y²+xy)
If x : y : z = 6 : 7 : 11, and (2x + 3z) = 180, then find the value of y.
If 1/(x+ 1/(y+ 1/z)) = 13/30, then find x+y+z= ?
If (a + b) = 9 and ab = 14, find the value of (a² + b²).
Find the number of zeroes in 18 × 125 × 20 × 32.
