Question
An Indian importer observes the following quotes in the
interbank market: Direct Quote in India:Β 1 USD = βΉ83.50 Indirect Quote in India:Β 100 INR = 1.22 USDΒ Β Β Β Β Β Β Based on these quotes, which of the following statements is mathematically accurate regarding the relationship between these two rates?Solution
A Direct Quote is 1 πΉππππππ ππππ‘ = π π»πππ ππππ‘π i.e. 1 USD = βΉ83.50. An Indirect Quote is 1 π»πππ ππππ‘ = π πΉππππππ ππππ‘π i.e. βΉ100 = 1.22 USD Β or βΉ1 = 0.0122 USD Β To compare, find the Implied Direct Rate from the indirect quote: Β = 1/indirect quote = 1/0.0122 = 81.967 Β As βΉ81.97 (as calculated) is lower than βΉ83.50 (Directly quoted), the USD is cheaper via the indirect route, creating a potential arbitrage opportunity.
What will come in the place of question mark (?) in the given expression?
(β676 of β144 Γ· 13) of 2400% = ?Β
(47.5 ÷ 9.5) × (78.5 ÷ 15.7) + 475 = ? + 15% of 150
20% of (β9216 + ?) = 24
20 × 224 ÷ 16 – 50 = ? + 100
...144 (1/2) Γ 14 β 28 = 7 Γ ?Β
- What will come in place of the question mark (?) in the following questions?
75%Β ofΒ 240 + 30 = ? Simplify: 3/4 + {5/6 Γ· (2/3 β 1/6)} β 7/8
- What will come in place of (?) in the given expression.
(β of 450) β (β of 300) = ? 1555.5 + 1000.8 – 1354.3 = ? + 52
116 ÷ 280 of 1/2 + 3/5 × 5/3 = ?
