    A candidate who scores 30% fails by 5 marks, while another candidate who scores 40% marks gets 10 more than minimum pass marks. The minimum marks required to pass are—

    Solutions

    Let x = total marks

    A candidate who scores 30% fails by 5 marks

    first candidate score = 3x/10

    it means minimum passing marks = 30x/100 + 5 = 3x/10 + 5

    candidate who scores 40% marks gets 10 more than minimum pass marks

    it means,

    40x/100 = 10 + 3x/10 + 5

    2x/5 - 3x/10 = 15

    (4x-3x) / 10 = 15

    x = 150

    minimum passing marks = 3x/10 + 5 = (3*150) / 10 + 5 =450/10 + 5 = 45 + 5 = 50

  • Question 10/10

    DIRECTIONS: Study the following information to answer the given questions.

    In a certain code language, 

    ‘heavy rain leads to rivers full’ is written as ‘nip tip vo ki su da’,

    ‘full enjoy in rain’ is written as ‘chi su pit tip’, 

    ‘all rivers in danger’ is written as ‘zo pit nip kho’, 

    ‘rain leads all cool’ is written as ‘vo su phi kho’.

    What is the code for ‘danger’?

    Solutions

    heavy rain leads to rivers full = nip tip vo ki su da _____(1)
    full enjoy in rain = chi su pit tip _____(2)
    all rivers in danger = zo pit nip kho _____(3)
    rain leads all cool = vo su phi kho _______(4)
    From (2) and (4),rain = su
    From (1) and (4),leads = vo
    From (1) and (3),rivers = nip
    From (2) and (3),in= pit
    From (3) and (4), all = kho 
    So, from (3),danger = zo
    From (4),cool = phi
    From (1) and (2), full= tip 
    From (2),enjoy = chi
    From (1), heavy to = ki da
