What will ratio between age of Ram and Mohan after three years?
Statement I. Ratio between age of Ram and Mohan four year ago 4 : 5, while six years hence ratio between 1/2 th of Ram age and 1/4 th of Mohan age will be 5 : 3.
Statement II. Ratio between present age of Ram and Mohan is 4 : 5 and between Mohan and Sohan is 5: 6. Four years hence average age of all three will be 34.

From I. Let age of Ram and Mohan be 4x and 5x respectively.
What will be volume of cylindrical vessel?
Statement I. Radius of cylindrical vessel is equal to side of square, which perimeter is 28 cm less than perimeter of rectangle. Height of cylindrical vessel is equal to breadth of rectangle.
Statement II. Ratio between Length and breadth of rectangle is 4 : 3 and that of between breadth of rectangle and side of square is 9 : 7.
From I. Radius of cylindrical vessel = side of square 2(l + b) – 4a = 28 Height of cylindrical vessel = breadth of rectangle From II. Length: breadth of rectangle = 4: 3 Breadth of rectangle: side of square = 9: 7 Length: Breadth: side of square = 12: 9: 7 ATQ – 2(12x+ 9x) – 4×7x = 28 x = 2 cm Radius of cylindrical vessel = 14 cm Height of cylindrical vessel = 18 cm
What is the cost price of mobile?
Statement I. Shopkeeper marks the price 24% above the cost price and allow a discount of . If he would mark 15% above the cost price and allow same discount, then he got Rs. 315 less profit.
Statement II. Shopkeeper marks the price 60% above the cost price and allows two successive discounts of 25% & and made profit of Rs. 200.
What is average of x, y and z ?
Statement I. Ratio between x and y is 4 : 5 and between y and z is 5 : 3.
Statement II. Value of 1.5(x + z) – 1.25(y) equal to 20% of 148.75.
Ratio between length of two trains is 3 : 4. What will be difference between their lengths?
Statement I. Longer train cross a 240 meter long bridge in 20 sec.
Statement II. Speed of longer train is 72 km/hr.
Let length of two trains be 3l meter and 4l meter From I & II –
l = 40 meter So, From I & II together we can determine the difference between length of two trains.
What will come in place of the question mark (?) in the following questions?(You are not expected to calculate exact values)
23.98% of 550.03 + 125.03% of 123.98 = (16.03)2 + √?
? % of 640.08 + 43.98 % of 300.11 + (8.02)2 = (21.96)2
819.06 + 277.02 - √? = (32.01)2
