x BZ means ‘AZ is the sister of BZ’; AZ ÷ BZ means ‘AZ is the daughter of BZ’ Which of the following expressions means ‘UY is the daughter of QY’?Solution
QY – ZY ÷ UY x KY à Incorrect, because the last condition UY x KY is not satisfied. QY – ZY x UY ÷ KY à Correct, because it satisfies all the given conditions. KY – ZY ÷ UY x QY à Incorrect, because the condition UY x QY is not satisfied. KY – UY ÷ ZY x QY à Incorrect, because the condition ZY x QY is not satisfied. ‘QY – ZY x UY ÷ KY’ represents that ‘UY is the daughter of QY’. Hence the correct answer is (B).
- What will come in the place of question mark (?) in the given expression?
62.5% of 120 + ? = (720 + 90) ÷ √36 {(123 + ? × 28) – 1254} × (2328 ÷ 97 – 13) = 8195
(560 ÷ 32) × (720 ÷ 48) = ?
{(? × 15) + (? × 45)} – 120 = 360
Find the simplified value of the following expression:
72 + 132 X 4 - {232 + 172 - 402
? = 2640 ÷ {(35% of 1240) – 170}
- What will come in the place of question mark (?) in the given expression?
?² = 28% of 35% of 4500 72 x 60 x 22 x 32 =?
72.5% of 400 – 23.25% of 1020 = 105% of ?
(72 × 52 + 1555 )/(79+60) = 2000 ÷ ?
