Question
Balu’s investment is half of Raj’s investment. After
4 months, Raj leaves and Ram joins with an investment of X amount (not in the same month). If the profits of Balu and Ram are equal, and Raj’s initial investment is Rs. 8400, what will be the value of X? A) 8400 B) 5600 C) 4800  D) 3600Solution
Balu’s investment = 1/2 * Raj’s investment Balu’s investment: Raj’s investment = 1: 2 Profit ratio = (4200 * 12): (8400 * 4): (X * certain months) Possible months = 1, 2, 3, 4, 5, 6, 7 From Option A => (4200 * 12)/(8400 * certain months) = 6 months This option satisfies the given condition. From Option B => (4200 * 12)/(5600* certain months) = 9 months This option does not satisfy the given condition. From Option C => (4200 * 12)/(4800* certain months) = 10.5 months This option does not satisfy the given condition. From Option D => (4200 * 12)/(3600* certain months) = 14 months This option does not satisfy the given condition.
√3598 × √(230 ) ÷ √102= ?
Simplify the following expressions and choose the correct option.
45% of 640 + (2/5 of 350) = ?
√225 + 27 × 10 + ? = 320
32 X 25 ÷ 4 + 12 of 30 = ? X 5 - 30Â
1440 ÷ 12 + 540 ÷ √36 + ? = 180 * 3
4567.89 - 567.89 - 678.89 = ?
- What will come in place of the question mark (?) in the following questions?
18×4+96÷8=? ((12+12+12+12)÷4)/((8+8+8+8+8+8)÷16) = ?
9999² + 1111² =?
- What will come in the place of question mark (?) in the given expression?
(120 - ?) ÷ 2 + 35 = 86 - 11
