ATQ, (7x –6200)/(9x – 7800) = 3/4 28x – 24800 = 27x – 23400 x = 1400 Savings of Vicky = 7x – 6200 = 9800 – 6200 = Rs. 3600 Savings of Vinnay = 9x – 7800 = 12600 – 7800 = Rs. 4800 Hence Required difference = 4800 – 3600 = Rs.1200
431.98 + ? – 15.04 = 864.93 – 368.01
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
44.98% of 399.98 = ? x 19.98 - (39.98% of 2499.98)
`root(3)(725.87)` `-:` `sqrt(81.033)` + 49.88% of 809.77 = ? - (14.78 `xx` 52.2)
672.35 ÷ 24.03 × 12.99 – 1288.28 ÷ 13.94 = ?
(√845 ×19.932+ √4230 ×14.385)/(√1765 ×4.877 ) = ?
54.8% of 800 - √(?) = 33.98% of 400 – 12.42% of 300
12.03 x 4.21 +19.95% of 300.05 = ?
Which of the given trigonometric identities is incorrect ?
1. tan2 θ = sec2 θ - 1B. cosec2 θ = 1 + cot
