    A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.

    MNOP, NOPQ, OPQR, ?
    Solutions
    Pattern of series is:
    (MNOP) ⇒ M + 1 → N, N + 1 → O, O + 1 → P
    (NOPQ) ⇒ N + 1 → O, O + 1 → P, P + 1 → Q
    (OPQR) ⇒ O + 1 → P, P + 1 → Q, Q + 1 → R

    In similar way, 
    (PQRS) ⇒ P + 1 → Q, Q + 1 → R, R + 1 → S
    So, PQRS is the missing term.

    If January 1st is a Friday, what is the first day of the month of March, in a leap year?
    Solutions
    total number of days between 1st January and 1st March in a leap year
    30 days in January(after 1st January)+29 days of February + 1st March= 60 days 
    since after every 7 days there will be a friday, we divide total number of days by 7 and remainder obtained are the number of days after friday 
    so the number of days after friday will be 4 
    saturday, sunday , monday, and finally tuesday
    So the required day is tuesday

    Another Approach:
    after every seven day there is a friday.
    so after 1 there will be friday on 8 jan, 15 jan , 22 jan , 29 jan , 5 feb , 12 feb, 19 feb, 26feb
    since 26th feb is a friday 
    27feb - saturday
    28feb - sunday
    29feb - monday
    1 march- tuesday

    Hence, option C is the correct answer.

  • Question 5/10
    1 / -0.33
    What must be the length (in cm) of the diagonal of a rectangle if its area and breadth are 120 cm2 and 8 cm respectively ?
    Solutions
    Area =120 cm2 and breadth = 8 cm
    Area = length × breadth
    120 = L × 8
    L = 15 cm
    Diagonal2 = length2 + breadth2
    Diagonal2 = 152 + 82 = 225 + 64
    Diagonal2 = 289 = 172
    Diagonal = 17 cm
    Hence, option B is the correct option
