4V is the volume of the cuboid. Let the initial length, breadth and height of the cuboid be l, b and h respectively. ∴ Volume of the cuboid (V) = lbh After making changes, new length = 2l New breadth = b New height = 2h ∴ New volume of the cuboid = 2l × b × 2h = 4lbh ∴ New volume of the cuboid = 4VRead more
4V is the volume of the cuboid. Let the initial length, breadth and height of the cuboid be l, b and h respectively.
∴ Volume of the cuboid (V) = lbh
After making changes, new length = 2l
New breadth = b
New height = 2h
∴ New volume of the cuboid = 2l × b × 2h = 4lbh
∴ New volume of the cuboid = 4V

Explanation: Let the quantity of the wine in the cask originally be x litres Then, quantity of wine left in cask after 4 operations =[x(1−8/x)⁴]litres ∴[x(1−8x)⁴/x] = 16/81 ⇒[1−8/x]⁴=(2/3)⁴ ⇒x=24
Explanation:
Let the quantity of the wine in the cask originally be x litres
Then, quantity of wine left in cask after 4 operations =[x(1−8/x)⁴]litres
∴[x(1−8x)⁴/x] = 16/81
⇒[1−8/x]⁴=(2/3)⁴
⇒x=24

Explanation: Let the cost of a table and that of a chair be Rs. x and Rs, y respectively. Then, 2x + 3y = 3500 ...(i) and 3x + 2y = 4000 .....(ii) solving (i) and (ii) we get x = 1000, y = 500
Explanation:
Let the cost of a table and that of a chair be Rs. x and Rs, y respectively.
Then, 2x + 3y = 3500 …(i)
and 3x + 2y = 4000 …..(ii)
solving (i) and (ii) we get x = 1000, y = 500

Correct Answer: 7 183.5÷273.5×63.5=2?183.5÷273.5×63.5=2? (1827×6)3.5=2?=(4)3.5=2?(1827×6)3.5=2?=(4)3.5=2? [adinserter block="7"] (22)3.5=2?=>(2)7.0=27=>?=7
Correct Answer: 7
183.5÷273.5×63.5=2?183.5÷273.5×63.5=2?
(1827×6)3.5=2?=(4)3.5=2?(1827×6)3.5=2?=(4)3.5=2?

Explanation: The given number series follows a pattern that 196, 169, 144, 121, 100, 81, ? -27 -25 -23 -21 -19 -17 => 81 - 17 = 64 Therefore, the series is 196, 169, 144, 121, 100, 81, 64.
Explanation:
The given number series follows a pattern that
196, 169, 144, 121, 100, 81, ?
-27 -25 -23 -21 -19 -17
=> 81 – 17 = 64
Therefore, the series is 196, 169, 144, 121, 100, 81, 64.

Correct Answer: 4162141621 L.P. = Rs. 1400 After Ist Discount = 90/100×1400 = Rs. 1260 S.P. = Rs. 1200 [adinserter block="7"] Additional Discount % = 1260−1200/1260×100 = 10021
Correct Answer: 4162141621
L.P. = Rs. 1400
After Ist Discount = 90/100×1400
= Rs. 1260
S.P. = Rs. 1200
Additional Discount % = 1260−1200/1260×100
= 10021

Correct Option: C Let the number be 3N and 4N. Then, 3N + 4N = 420 ⇒ 7N = 420 ⇒ N = 60 ∴ Greater number = 4 x 60 = 240
Correct Option: C
Let the number be 3N and 4N.
See lessThen, 3N + 4N = 420
⇒ 7N = 420
⇒ N = 60
∴ Greater number = 4 x 60 = 240
