  • Question 1/10
    1 / -0

    Cost price of an article is Rs 3600. It was sold at a profit of 15%. If the article was sold at a discount of 8%, then what is the marked price (in Rs) of the article?

    Solutions

    Selling Price = Cost Price × (100+Profit) %
    ATQ,
    Selling Price = 3600 × (100+15) %
    So, Selling Price = 4140
    Selling Price = Marked Price × (100-Discount) %
    ATQ,
    4140 = Marked Price × (100-8) %
    So, Marked Price = 4140 × 100/92
    = 4500

    In an election, a candidate got 62% of the total votes polled and won the election by 35640 votes. The total number of votes cast, if no vote is declared invalid, is:

    Solutions

    let the total votes polled=100units

    then the candidate who loses the election got the % of vote=38units
    required difference =62-38=24units
    so 24 unit =35640
    1 unit= 35640 / 24 = 1485

    If the acceleration due to gravity on the surface of earth is g, then the acceleration due to gravity on the surface of a planet whose mass is same as that of earth and radius is twice as that of earth is _________________.

    Solutions

    As per the formula, Earth’s g= GM/R². Here g’= GM/4R². So the acceleration is g/4 than that of the earth.

    In an alloy, the ratio of copper and zinc is 4 : 3. If 1.250 kg. of zinc is mixed in 17.5 kg. Then the ratio of copper and zinc will be–

    Solutions

    Total quantity = 17.5 kg.  

    Quantity of Zinc in mixture =  17.5/7 × 3 = 7.5 kg.

    After adding 1.25 kg. Zinc = 7.5+1.25=8.75 kg.

    Quantity of Copper in mixture =  17.5/7 × 4 = 10  Kg. 

    Ratio of copper and zinc =  10/8.75

    = 8: 7

    The bonds formed by the elements having larger atoms are:

    Solutions

    Bonds are attractive forces which keep the two atoms together in the molecule. In general, as the distance between to objects increases, the attractive forces between them gets decreased. As we know that the distance between the nucleus of two bonded atoms is known as bond length that means greater the bond length, weaker will be the bond.
